If I was 18 again, I'd be packing up to drive to Utah. I'd sweep floors, take out trash, wash cars, clean tools, all for free just to get to work for this guy. What a teacher! I can only imagine what you could learn in a year.
If you cannot get a job with someone like Dave. Get some education, trade school. If that isn’t possible. Get a job with someone, somewhere, somehow, doing work in your chosen career. That way you can get experience in the job. Then listen,learn, even if it is not the best shop you can learn something. Hang in there a year maybe two. You don’t want to look like you can’t hold a, job thats not a good thing. Then the Daves are going to look at you different. Be honest tell the interviewer what you want from the job, have that in mind before the interview. Good jobs are hard to find. You have to work hard at finding a good job. Then you need to work hard to keep it. This is advice from a 72 year old retired electrician for a young person. But it will still apply to a job seeker in skilled trades. One of the great mistakes our country has made is to stop using trade schools and apprenticeships. Good luck to you!
Knowledge you can only get by doing, experience,and passion for your trade,I wish I had someone like him in my life as a kid and now for that matter,I want so badly to have a solid mechanic teach me what I don't know,I would absorb that knowledge like a sponge,very humbly at that,I definitely have learned a lot on my own,but know I have so much to gain from someone like Dave 💯🤟💪💪💪
These longform videos are fantastic. Such a great teacher! Here Dave is teaching not just how to work on a differential but also how to guide your young employees. Thank you!
@@DavesAutoCenterCentervilleI used to be a real asshole when training people in the shop I work in as a welder. With experience…and age…I’ve taken to more of a stern when needed but also a mentor type of training. Nice job.
😢Our teacher was a wolf in sheep's clothing! The lazy folks and talkers got cursed out and books slammed on their desk. The workers, got a lot of work. In the end, we all made it out with the skills needed to fix cars. But nowadays the newer computerized parts and electrical problems are extremely hard or impossible to fix in the time allowed. I had to do a ABS pump bleed and brake booster adjustment on a FORD 14 times, and slam on the brakes at 67 mph 8 times before the pedal got hard on the new module 😢
@@Bandwidth24 I’m going to show my age ABS the first time I saw it was on the aircraft I worked on, there were zero on the ground vehicles that had it. 🤣
All i can say Dave is my Dad has gone to be with the lord and everything you do is how my dad taught me. Im retired now but I wrenched for close to 45 years and ended my time working on gas and steam turbines with GE. My dads love and knowledge carried me through life. Its like seeing my dad when I watch you. Thank you and god bless
Definitely the best way to learn the trade! Now everyone wants you to go to college 😂 real shop time can be less attractive compared to college time for some big corporations nowadays.
Gonna be honest. The way that you train your new mechanics is how I wish I had learned. I went to professional schooling and learned more in the shops than I ever did in school. Well done sir.
“If it wasn’t hard, everyone would do it. It’s the hard that makes it great." Thanks Dave, your knowledge and presence is what make these videos great to watch. Thank you sir.
Nice job Dave! I've been setting up and building differentials for over 25 years and I just love watching how others take on the same jobs. I never know if I might learn something new.
This guy is a true Master teacher . As a plumber/pipefitter at a VA hospital, i never trust someone else's diagnose. Verify it myself . And btw , i teach the apprentices, you dont trust mine , verify it yourself . Ive taught plumbing code for over 23 years . When asked , aren't you afraid that you are teaching your competitors who are much younger than you ? I then ask , guess what this 63 year old man has that you guys dont ? You cant buy it , steal it either . What ? Experience ! We try to pass it along but at some point , there is no substitute for on the job training. Love watching this . Great teachers dont have to act like they care and their students know it . I would bet this guy once dreamed of having some old master mechanic mentoring him back in the day . He became that guy . Ask me how i know .
@waterheaterservices had a Rheem performance gas water heater kick my butt , TRD . I'm like, really ? Fancy mouse trap . Oh well . Turd herders salute you sir
Your patience with a new tech is commendable. We all have to learn how at some point. Tell what you are going to do, explain why it matters, demonstrate how it's done, allow student to perform task, and then reinforce what was done. It always works out well when done like that. Good teaching/coaching techniques.
Mr. Dave, I have been an Automotive Technician for 30 years, and I enjoy listening to the way you articulate the process, sir. I currently work at Ford. I would love to be involved with what you are doing. I'll be watching. Anyone who thinks they can't learn something every day is lying to themselves. Heck, we all have different ways of skinning a cat. Keep doing what you're doing, sir. Good luck on Discovery. Nice video.
That younger man def learned some great things today!!! I love to see someone that cares about quality and honesty in the business of working turning wrenches!!! Great job teaching!!!
The hardest thing for a mechanic, let alone a learner tech, is to work under scrutiny. The cameras are showing the world how you work!😂 Kid is doing great. The enthusiasm he has is good stuff. Dave is a super instructor..
This is an educational masterclass. I've not yet found anywhere better to get all this much knowledge, experience and understanding all in one place. Many thanks Sir.
Dave... (Speaking as a retired 30 year, old school veteran mechanic and 15 year instructor)...you're a fantastic purveyor of knowledge! Love how you take an obviously complete rookie and teach him the right way to perform the task at hand. This will keep him from learning bad habits or unwarranted short cuts. Obviously he will still need a lot on on-vehicle experience to become a competent mechanic. However, with you tutorial skills and dedication, he should come out the other end a TRUE master mechanic.
That is one lucky young Tech to have a teacher like Dave go through this procedure with him. Dave, you are an excellent teacher. I wished that I had someone like you explaining and showing me how to do something like this years ago.
@@startingtech3900I have worked for shops like Dave’s. The owners gross business revenue was over 1M a year. And their take home was good. But the business is very demanding, lots of time and skill has to be continuously invested. Along with equipment. It is a roller coaster. I started my own business doing something in the automotive field. What I do is far less stressful with low risk and high pay out. And also excellent quality of life. It’s in the niches that great success can be found.
Dave, i really appreciate you teaching the younger generation what we learned from the older, more experienced mechanics of our day. The world needs us and its awesome that you are passing down the knowledge.
All that I have to say is this: The only things that anyone would have in the heart about having this kind of teacher, is gratitude and respect. such a great channel.
One thing that makes this such a good video is that you are teaching someone and anticipating directly before you give a quick concise explanation then keep it moving w o any bs. No stopping in the middle to discuss useless things. All info on target.
I hear ya, this is top notch content. I got premium to avoid ads for my family. It became too much. In some ways RUclips has gone the other way compared to the old days.
Love seeing people teaching. One tip for the young lad is I keep an old bearing race for bearings I do like hub bearings and diff bearings and cut a slit in them with a 1mm cutting disk. Then you can use that as a drift or in a press to fit new bearings like at 17:00. Dave did exactly what I would have done at 22:00.
You know why I love watching your videos?? Because you live by the modo you only keep what you have if you give it away!!! The fact that you explain you repairs in detail says allot about your soul!! You Mr are a kind thankful soul that’s why you’re so successful you are a rare breed I hope you see this message keep teaching professor!!!! I watch all your vids because I know you’re teaching good knowledge !!!!
You are a great teacher, you not only show the correct way to do a job but the safety aspect as well. Safety should be "paramount to everyone", doing this type of work! 👍👍
Mr dave, you are incredible.. As someone that's worked in about 20 shops, Every now and then you find a MONSTER of a mechanic. Mr dave is one of those people.. keep up the great work
Howdyyawl from the land down under. Well done Dave! The young fella learnt alot. Be proud of him. We run a farm in OZ & you have to fix every thing. Nice to see someone who is willing to teach. Keeping it real😊
Yes Sir. Grew up on a farm in the 70's and 80's. We maintained and repaired everything ourselves. I chose a different carrer, but that knowledge and resourcefulness has carried me through. Retired now and still enjoy wrenching on all my vehicles/motorcycles.
I enjoy watching Dave and raian Ray only! .was a GM tech for 13.years. Independent shop tech for another 10 then a fleet owner operator of class 8 dump trucks and log haulers. But I still enjoy Dave and Rainman Ray. Too old and broke up to do this work everyday but I enjoy seeing these.guys do their thing. Way to go guys. Wish I wasn't so old and broken up
I also do the same procedure as you with the screwdriver to the ear except I always used a wooden dowel. It's reassuring to see someone as accomplished and thorough as yourself doing the same. Your operation is the pinnacle of the trade! I wish there was a service center such as yours available to me when I was a young man getting started. Keep up the good work! Thanks and Best Wishes, Mark
Great video Dave. Only problem I see if set the example with the new guys on safety. I saw plenty of shards of brass flying when pounding on that drift without proper eye protection or when using the press. Your eyes are your most valuable assets besides your hands so you have to protect them at all costs. It great to see the wealth of knowledge being passed on to the new guys who are hungry and willing to learn.
Howdyyawl from the land down under. Good job. Good teacher. I use a short broom handle to listen for crook rollers especially when checking in large machinery. I find sound travels better through wood than metal. But that is a preference. Good video. Keeping it real 😊
Love the patience and knowledge you are trying to give the young man and just the overall positivity you are putting out there. Really enjoy the channel
thanks for the vids Dave. Please keep em coming. I've been a backyard hobbiest do it yourselfer my whole life and can't stop learning about this stuff. Appreciate the detailed explanations of everything you do! Cheers
Another great video Dave. Back here in the UK July 1972 I was just starting my apprenticeship as a mechanic with a Ford main Dealer in Enfield North London. In 1970 Ford UK had launched its latest model - the Cortina MKIII but by late 1972 these vehicles where suffering with increased rear axle noise levels. On the TSB's it was referred to as "axle howl"! These axles were know as the Salisbury axle and is much the same as the one in your excellent video. For the next 18 months plus we were inundated with dozens of axle rebuilds every month and all under Fords warranty. Watching your video takes me right back to those very hazy days where we could rebuild a Salisbury axle almost blindfolded. Pre load, backlash and collapsible spacers are all so familiar! Thanks so much for the trip back in time. Stay safe. David. Hertfordshire UK
High drag from the tight pinion bearing will make heat and burn up the seal. The higher numerically the ration the more sped and more heat. I,ve made this error with new bearings and put in a replacement seal, crush sleeve and new nut to resolve.
Love your videos! For future reference check out pinion/carrier bearing pullers. One of my favorite tools in the shop! No harm done to the bearings or shims and comes off like butter with minimal effort.
@@brianb5779 there’s several manufactures that make it now with various price ranges…type in pinion/carrier bearing puller on google and you’ll see all the options. Most are pretty universal for average car and truck stuff.
I thoroughly clean after diagnosis, before disassembly When cutting those bearing cages, I use side cutters and it cuts them like butter Can’t slip and nick your gears. Lol That crush sleeve is why there was no shims in the bearings Great video guys
16:13 Definitely a bit painful to see the new guy ding the bearing race. Most noticeable on the top side. Doesn’t look like the mark affects the bearing surface, but that dude definitely needs to be more careful in the future.
@jotham123 something other than using a punch. But yeah using liquid nitrogen to get it extremely cold so it shrinks would be would definitely work. I understand that sometimes you have to drive it in but use something that fits around the outer bearing like onto the face like a huge socket and drive it in evenly.
This is so rare. So often kids are given a job like this and are expected to get it right without any real training. I can also guarantee you this will not be the only time that Dave helps him with this. Takes a couple of times to drill it in and that's okay. I can already tell this young man is going to make an excellent mechanic due to natural talent and great instruction!
@@jetterbuglovejust done this much pre-load on my truck and made it half a mile and the pinion bearing locked up. All brand new bearings. Time to tear it back down and definitely will only do 25 inch pounds on pre load
This is awesome to seen Dave teaching this young man, he’s direct but patient and makes sure his student is taking in the wisdom Dave is blessing him with.
I love your videos in general, but this one made me wince. I suggest you buy and use a bearing race installer kit and seal installer kit. Using a punch to install a bearing race is not the best approach. Heating a bearing is really a last resort. Don't beat me up, but I have rebuilt hundreds of differential units, and there are a lot of things I would have done differently. Possibly, stick to your expertise of rebuilding engines!
Such a great video! I love how the young tech is absorbing all the educational.. not many care to do so nowadays. Keep the videos coming! I also love the analogy of cleaning up the old mess, not many care to do that these days.
I am an electronics engineer of 36 years hands on, with a decent cross over into mechanical. I just love the way you mentor the young guy. Every experience is a learning opportunity for a youngster... you cannot get that old guy knowledge any other way & us old guys need to make sure we pass it on to tomorrow's old guys. We all remember the first days when we spent what seemed eternity sweeping up, fetching stuff & making the tea... but it does pass. It is the time you connect to your most valuable moentor... that old guy you will never forget & when his days of getting dirty are done, he will remember with immense pride how he turned you into the great mechanic or engineer you will become.
Us "old guys" are still relevant. Just like Dave said, "my old guy senses". These are developed over 20+ years of doing stuff like this. To train a young person with these skills is so valuable. Young people these days usually don't have a Dave to teach them, and then must learn as they go all the while pissing off customers. Love the teaching, Dave. Every step you went through I was saying it out loud as if I was helping to teach this young buck. LOL Keep doing what you are doing!
I am absolutely not a mechanic, in fact I am a software engineer, but I am just enamored with this channel. The mental methods that Dave displays can be applied to almost anything. Keep it up, boys.
I was born in the Salt Lake Valley and raised in eastern Utah in the Uinta Basin where I worked for my dad in his garage and I see you teaching just like he would do with me, he served on a Navy Destroyer in WW2 and as a result he never graduated high school, the local community college wanted him to teach auto mechanics but couldn’t hire him without a high school diploma, I have always thought about the loss of knowledge and his way of teaching as it exactly what I see from you, your mechanics are getting paid while you school them, I took everything I learned from my dad and applied it to my trade as a heavy lift helicopter mechanic and it all starts with being clean and organized, I try to emulate what I learned from my dad and what I see from you in how I work and train the new guys coming in. After 30 years living in Oregon I am now back living in Utah and still working in Oregon but the lessons are here for every one and it’s this start clean and stay organized and be the professional you are being paid to be. I’m sorry this was long winded but I really wanted to highlight how your teaching, very nicely done, thank you for what you do and how you do it.
Dave takes so much respect in his career. He spent so much time explaining to the young gentleman with him how to do the job right. Based on my time as a technician, we learnt some of this in Automotive school, but that was only during each semester. After that things got forgotten until you went in the industry again. Most dealerships will just tell you to read the service manual and take something apart and put something back based on that while that is true, it’s so much more confidence inspiring when you have a mentor teaching you the way he did.
Awesome content and to the lucky apprentice appreciate what Dave is imparting, the knowledge of time spent on the wrenches makes your life sooo much easier 👍
Loved this video! For the last 40 years, I'd read on how this procedure is done. Finally, you have created a video on how to actually do the job! Thank you for a great and intuitive visual lesson.
Got to love a customer who doesn’t wash the mud from the under carriage before heading to a mechanic. Open diff on lifted 4x4 makes more sense now lol. Great video.
I've been off the tools a few years but I can tell you know what you are talking about Dave, and you are hands on still. One trick I found was grinding a touch off the outside of old races before I use them to drive new ones in. It makes them loose but they still do the job. I had some get stuck and its a pain to get out depending on the housing design. I hope you apprentice realises all the knowledge he is picking up rather than just changing oil all day.
I was mechanic over40 yrs and done many differential rebuilds Your coverage is best I've seen on any program Very accurate in detail and thank you for no loud guitar music Great job enjoy your interesting videos !
I've rebuilt a lot of differentials, but its been a long time since I've watched another professional do one from start to finish, and I've never seen a craftsman technician do one. Its great to see what your doing wrong (if anything) and what your doing right (if anything)!
bravo Dave ! Dave correctly explained the same principles of tools, procedures to achieve proper preload, run-out, and back-lash. Dave just did what a lower unit on an outboard (boat) motor has. Amazing stuff, Dave!
This man right here mr dave is such an awesome technician/teacher. I went to school for automotive diagnostics way back. I dont even work on cars but love watching your videos
If I was 18 again, I'd be packing up to drive to Utah. I'd sweep floors, take out trash, wash cars, clean tools, all for free just to get to work for this guy. What a teacher! I can only imagine what you could learn in a year.
Amen to that that..
@@mikepair8837
AMEN INDEED my man👍
Never work for free!! If you’re a good worker they will be wishing they were paying you to work for them.
If you cannot get a job with someone like Dave. Get some education, trade school. If that isn’t possible. Get a job with someone, somewhere, somehow, doing work in your chosen career. That way you can get experience in the job. Then listen,learn, even if it is not the best shop you can learn something. Hang in there a year maybe two. You don’t want to look like you can’t hold a, job thats not a good thing. Then the Daves are going to look at you different. Be honest tell the interviewer what you want from the job, have that in mind before the interview. Good jobs are hard to find. You have to work hard at finding a good job. Then you need to work hard to keep it. This is advice from a 72 year old retired electrician for a young person. But it will still apply to a job seeker in skilled trades. One of the great mistakes our country has made is to stop using trade schools and apprenticeships. Good luck to you!
Absolutely 💯
Dave is an excellent teacher of our great industry.
Appreciate that. I would like to give back to an industry that has given so much to me

Your operation is the pinnacle of the trade! I wish there was a service center such as yours available to me when I was a young man getting started. Keep up the good work! Thanks and Best Wishes, Mark
Passing on Old School knowledge. The world needs a lot more of that. That is awesome.
Great video Dave. Only problem I see if set the example with the new guys on safety. I saw plenty of shards of brass flying when pounding on that drift without proper eye protection or when using the press. Your eyes are your most valuable assets besides your hands so you have to protect them at all costs. It great to see the wealth of knowledge being passed on to the new guys who are hungry and willing to learn.
Good point. The young man should have had on eye protection.
Gloves too early in a career can't hurt. Ear protection too coming from a 74 yr old who's lost 25% of his from loud noises.
Makes you appreciate the engineered beauty of bearings and gears! What a job they do for us!
“My old man shit tells me we’re on money” I love it. Dave you’re awesome!! Love your sense of humor!!
Howdyyawl from the land down under. Good job. Good teacher. I use a short broom handle to listen for crook rollers especially when checking in large machinery. I find sound travels better through wood than metal. But that is a preference. Good video. Keeping it real 😊
Love the patience and knowledge you are trying to give the young man and just the overall positivity you are putting out there. Really enjoy the channel
I appreciate that
I really appreciate a mechanic who takes pride in his work. Well done dave teaching the youngsters.
thanks for the vids Dave. Please keep em coming. I've been a backyard hobbiest do it yourselfer my whole life and can't stop learning about this stuff. Appreciate the detailed explanations of everything you do! Cheers
Thanks, will do!
These mechanics are lucky to have a good teacher like Dave
I hope this young man understands what a privilege it is to work under someone like this
Dave is a great instructor. He teaches how, and why.
Another great video Dave.
Back here in the UK July 1972 I was just starting my apprenticeship as a mechanic with a Ford main Dealer in Enfield North London. In 1970 Ford UK had launched its latest model - the Cortina MKIII but by late 1972 these vehicles where suffering with increased rear axle noise levels. On the TSB's it was referred to as "axle howl"!
These axles were know as the Salisbury axle and is much the same as the one in your excellent video. For the next 18 months plus we were inundated with dozens of axle rebuilds every month and all under Fords warranty.
Watching your video takes me right back to those very hazy days where we could rebuild a Salisbury axle almost blindfolded. Pre load, backlash and collapsible spacers are all so familiar! Thanks so much for the trip back in time. Stay safe. David. Hertfordshire UK
Really great teacher thank you for sharing this with us 🇺🇸
A master at work. Dave is a great teacher, I’m learning as well.
Easily one of the videos on ram repairs I've seen!
No BS, all business - love it. So great to see a young face soaking in not only the technical information, but the attitude and approach to it. 👍
72 inch pounds on the pinion bearing is crazy high
Spec is 15 to 25
AAM 10.5-11.5 axle 25-45 inch lbs. Yep way high.
It’s a aam 9.25 front axle
11.5 is the rear axle
thank you for commenting, totally agree. This overhaul is busch league.
what would be the downside of going over?
High drag from the tight pinion bearing will make heat and burn up the seal. The higher numerically the ration the more sped and more heat. I,ve made this error with new bearings and put in a replacement seal, crush sleeve and new nut to resolve.
This guys a surgeon with this stuff.Cant beat 35 years of trial and error and good ole common sense.
Love your videos! For future reference check out pinion/carrier bearing pullers. One of my favorite tools in the shop! No harm done to the bearings or shims and comes off like butter with minimal effort.
Thanks for the info!
Do you have part # on what you use?
@@brianb5779 there’s several manufactures that make it now with various price ranges…type in pinion/carrier bearing puller on google and you’ll see all the options. Most are pretty universal for average car and truck stuff.
What exciting and awesome videos to watch. Thanks Mr. Dave!
When I saw all the writing on the parts my first thought was it’s been rebuilt before!!
Clam shell bearing puller makes removing those bearings extremely simple.
Love watching an experienced mechanic teach young guys about the "old man shit" Thanks for the great videos!
Not sure where you got your bearing preload on those new pinion bearings? 30 inch lbs would have been max on that
I thoroughly clean after diagnosis, before disassembly
When cutting those bearing cages, I use side cutters and it cuts them like butter
Can’t slip and nick your gears. Lol
That crush sleeve is why there was no shims in the bearings
Great video guys
16:13 Definitely a bit painful to see the new guy ding the bearing race. Most noticeable on the top side. Doesn’t look like the mark affects the bearing surface, but that dude definitely needs to be more careful in the future.
As someone who makes bearings for a living, especially bearings for differential, it makes me cringe watching them beat those outer rings in.😬
@@bearing_aficionado you'll probably fall over dead watching me install the bearing races😂
@@chiefknowstomuch 🤯
@@bearing_aficionado what would be a better way to do it? liquid nitrogen it and setup some sort of pull-in with a bolt setup?
@jotham123 something other than using a punch. But yeah using liquid nitrogen to get it extremely cold so it shrinks would be would definitely work. I understand that sometimes you have to drive it in but use something that fits around the outer bearing like onto the face like a huge socket and drive it in evenly.
This is so rare. So often kids are given a job like this and are expected to get it right without any real training. I can also guarantee you this will not be the only time that Dave helps him with this. Takes a couple of times to drill it in and that's okay. I can already tell this young man is going to make an excellent mechanic due to natural talent and great instruction!
when semi's came out with greaseless u-joints I thought they were crap but I seen a lot with over a million miles on them
You sir are a true gentleman. Sharing your lifetime of knowledge with a young mechanic. My hat off to you. Thank you sir.
Wow, thanks
That’s alot of pinion bearing preload 😮
Spec for new bearings on an aam 9.25 is 15-35 in/lbs. So yeah way off.
What does this mean? This is my son's truck, and the 4th comment I've seen saying this. I'm worried...@mwagner_87
Will honestly be fine. But could cause the bearings to wear out prematurely @jetterbuglove
@@jetterbuglovejust done this much pre-load on my truck and made it half a mile and the pinion bearing locked up. All brand new bearings. Time to tear it back down and definitely will only do 25 inch pounds on pre load
This is awesome to seen Dave teaching this young man, he’s direct but patient and makes sure his student is taking in the wisdom Dave is blessing him with.
I love your videos in general, but this one made me wince. I suggest you buy and use a bearing race installer kit and seal installer kit. Using a punch to install a bearing race is not the best approach. Heating a bearing is really a last resort. Don't beat me up, but I have rebuilt hundreds of differential units, and there are a lot of things I would have done differently. Possibly, stick to your expertise of rebuilding engines!
I would second that Dave's the best teacher, most thorough mechanic I've ever seen
49 years old and found good information today. Right handed marks the right side for memory.
Such a great video! I love how the young tech is absorbing all the educational.. not many care to do so nowadays. Keep the videos coming!
I also love the analogy of cleaning up the old mess, not many care to do that these days.
Thank you! I am doing new pinion bearings for the same reason this truck was being wrenched on! Sure appreciate watching and learning!
I am an electronics engineer of 36 years hands on, with a decent cross over into mechanical. I just love the way you mentor the young guy. Every experience is a learning opportunity for a youngster... you cannot get that old guy knowledge any other way & us old guys need to make sure we pass it on to tomorrow's old guys. We all remember the first days when we spent what seemed eternity sweeping up, fetching stuff & making the tea... but it does pass. It is the time you connect to your most valuable moentor... that old guy you will never forget & when his days of getting dirty are done, he will remember with immense pride how he turned you into the great mechanic or engineer you will become.
This guy shows a real class in the way he works and teaches, iv been loving the RUclips shorts for a good while now, never pass them up.
Us "old guys" are still relevant. Just like Dave said, "my old guy senses". These are developed over 20+ years of doing stuff like this. To train a young person with these skills is so valuable. Young people these days usually don't have a Dave to teach them, and then must learn as they go all the while pissing off customers. Love the teaching, Dave. Every step you went through I was saying it out loud as if I was helping to teach this young buck. LOL Keep doing what you are doing!
Dave's been turning wrenches for along time. A man with his knowledge is absolutely priceless!!
I love watching someone with this level of experience, and skill is so refreshing. These types of shops and technicians is what saves the industry.
I am absolutely not a mechanic, in fact I am a software engineer, but I am just enamored with this channel. The mental methods that Dave displays can be applied to almost anything. Keep it up, boys.
I was born in the Salt Lake Valley and raised in eastern Utah in the Uinta Basin where I worked for my dad in his garage and I see you teaching just like he would do with me, he served on a Navy Destroyer in WW2 and as a result he never graduated high school, the local community college wanted him to teach auto mechanics but couldn’t hire him without a high school diploma, I have always thought about the loss of knowledge and his way of teaching as it exactly what I see from you, your mechanics are getting paid while you school them, I took everything I learned from my dad and applied it to my trade as a heavy lift helicopter mechanic and it all starts with being clean and organized, I try to emulate what I learned from my dad and what I see from you in how I work and train the new guys coming in. After 30 years living in Oregon I am now back living in Utah and still working in Oregon but the lessons are here for every one and it’s this start clean and stay organized and be the professional you are being paid to be.
I’m sorry this was long winded but I really wanted to highlight how your teaching, very nicely done, thank you for what you do and how you do it.
Awesome video. Love hearing the very educational Mr Dave give his lessons. You're awesome Dave
Your teaching style is that of my mentor. Explains and leaves room for questions to be asked to reinforce what’s being told.
Dave takes so much respect in his career. He spent so much time explaining to the young gentleman with him how to do the job right. Based on my time as a technician, we learnt some of this in Automotive school, but that was only during each semester. After that things got forgotten until you went in the industry again. Most dealerships will just tell you to read the service manual and take something apart and put something back based on that while that is true, it’s so much more confidence inspiring when you have a mentor teaching you the way he did.
Awesome content and to the lucky apprentice appreciate what Dave is imparting, the knowledge of time spent on the wrenches makes your life sooo much easier 👍
Loved this video! For the last 40 years, I'd read on how this procedure is done. Finally, you have created a video on how to actually do the job! Thank you for a great and intuitive visual lesson.
We need guys like Dave to past this valuable knowledge down to the younger generation that is willing to listen .
I love the way you teach Dave! The young men that work for you are blessed!!
Sir, you are good teacher to the young mechanic, good to see how to remove and re-install the differential unit. Very good video.
Got to love a customer who doesn’t wash the mud from the under carriage before heading to a mechanic. Open diff on lifted 4x4 makes more sense now lol. Great video.
I've been off the tools a few years but I can tell you know what you are talking about Dave, and you are hands on still.
One trick I found was grinding a touch off the outside of old races before I use them to drive new ones in. It makes them loose but they still do the job. I had some get stuck and its a pain to get out depending on the housing design.
I hope you apprentice realises all the knowledge he is picking up rather than just changing oil all day.
His patience to detail is superb !!!!!
He is teaching me!!!!!
I was mechanic over40 yrs and done many differential rebuilds Your coverage is best I've seen on any program Very accurate in detail and thank you for no loud guitar music Great job enjoy your interesting videos !
I've rebuilt a lot of differentials, but its been a long time since I've watched another professional do one from start to finish, and I've never seen a craftsman technician do one. Its great to see what your doing wrong (if anything) and what your doing right (if anything)!
bravo Dave ! Dave correctly explained the same principles of tools, procedures to achieve proper preload, run-out, and back-lash. Dave just did what a lower unit on an outboard (boat) motor has. Amazing stuff, Dave!
This man right here mr dave is such an awesome technician/teacher. I went to school for automotive diagnostics way back. I dont even work on cars but love watching your videos
