Good job there Car Doc .my 2004 Towncar has 749.000 miles and I'm just doing first rear end job. My pinion gear finnally said fix me. It's been a hell of a good car.
Is that right 749K miles???!
@@grindhard4312 yes . I now have 849.000 miles on this car same factory engine . I use it for limo service so I drive every day. Been in limo business 41 years . I have got the best service from the 4.6 engines in Lincoln Towncar. It’s 2003 model ultimate L .
@@bigplayray777jackpot4 Wow!!! I bought an 03 Executive LTC from a limo service back in Jan and was SO skeptical of going through with it because it had 336K miles on it. But I needed a car and he assured me it well maintained and that she was a workhorse and reliable. 3K miles and camshaft position sensor later and she's running like a champ! I've been told these 4.6 engines can get 5-600K miles easily when taken care of, we shall see!!
Wow! Can't believe I watched the whole video...It was a real treat watching you work..Thankyou ☝
Thank you
I have only rebuilt 2 differentials in my career and this video was a great refresher. I don't understand why so many techs are afraid of differentials. They are great straight forward repair work - and you make it look very easy. Thanks for the video and the laughs.
Thanks, I have to admit im also one of those techs that gets a little uneasy when a diff problem rolls in. Mostly because there are so many subtle differences and special tools and procedures that come with these jobs. IM getting more comfortable all the time but am cautious none the less since its become such a specialty area due to tools, equipment and experience requirements. Just my two cents however I am confident this repair will get him another 100K down the road without issues.
Its not straight forward, theres specific feel, tools needed for many differentials, crush washers are a bitch, Proper ring and pinion distance via shims etc, He makes this look very easy.
Backlashing a blah . He is great at what he does

I might have missed it but the vid skipped that part, just showed the results. That’s fine, but it’s also the most persnickety part imho
27:00 if you're removing the bearing, just let the bearing push against the seal and pull them both out together with the slide hammer.
My Lincoln town car has rear seal oil leak , I replaced the seal and bearing today after I watch this clip.
Your video is brief and spectacular !!
Thanks for your video was very helpful !!
Awsome job. I can say i will be using this video for my crown vic repairs ty so much for taking time to explain everything and show everything step you are the bomb bro
Fantastic video! Your customers are lucky to have you as their mechanic. Job very well done, sir!
I have done axle seals and bearings, and pinion seals, but never the whole diff. You made it look easier than it probably is.
If I can do it you can do it. :)
Gee, Where have I heard that before? ha ha.
Car Doctor, thank you very much on all the knowledge and how to get it done, you helped me tremendously. that was a great key point on removing the abs sensor so I can get to the C-clip. you are the man , God Bless you. I changed my right side axle shaft 04 lincont town car 296000 miles!
Thank you so much. There are so many videos showing the removal of axles, but not one so far has shown that you have to loosen or remove that wheel speed sensor. I was about to put it back together and take it to a shop.... I couldn't get the axle to go in far enough :)
Ive never been in ANY crown vic that didnt have rear end noise lol! But this was a great informative and easy to watch video. Thanks for putting this up
they make 'em borderline screwed up... lol 🙄
Man I sure wish my 99 had that much space to work on the rear. The gas tank is barely 5inches away from the rear axle and I barely had enough room to get my wrench on there. But love the video. You do make it look easy.
I just picked up a 8.8 LS yesterday at the junk yard for 100.00 brought it home and pulled the drums and it had brand new brakes wheel cyl and hardware , had it out of the truck in 10 minutes thanks to my dewalt grinder, now I'm going to change 3.73 gear to 5.13
Mine developed noisy bearings around 180k. The transmission shop quoted $1000 to go through it and change everything. Instead, I found a good, low mileage rear axle from the salvage yard and installed it in an afternoon. $350. These 8.8's seem to be everywhere right now, and changing out the whole assembly saves a lot of work.
Nice clean professional differential job Tim! Once you have metal in the diff that's the only way to do it and now he can drive it all over & not have to worry about another bearing failure for quite a while!
Thanks, it so hard getting the case cleaned out.
Thank you very much for mentioning the normal in out movement I changed brakes and rotors on my 08 grand marquis and felt that,thinking the bearing might be going bad. It was ever so slight movement.
Good video. I'm not a mechanic but I've learned a lot watching you.
Awesome, I have a ‘whooping’ sound coming from my 2011 CVPI, especially noticeable around 35-40 mph and coming off the gas. Guess you diagnosed my problem , many thanks.
do you know what gear oil viscosity is in your diff??
@@glasser2819 should be 75W-140 on the CVPI. Full synthetic is best. Amsoil if it's my choice.
Very good video I appreciate it watching a experience skilled mechanic such as yourself do something give someone like me who has moderate mechanical ability the positive encouragement that I also can do that I know I can just watching someone such as yourself gives me the confidence please look into attaching a safety retaining cable for those return Springs on your press you can use the little saddle clamps and just a 8in garage door type Cable in case those Springs with break that will keep them in place so they're not flying across the shop just another little helpful hint again thank you for your expertise professionalism and the wonderful video I have to do a 93 F-150 pickup soon and this gives me the confidence to take it on thank you
Excellent video of Axle rebuilding!
Pure pro. Thank you for posting this.
Wow A nice job. You really had A job there. You are A great mechanic. I sure wish I lived near you. I feel bad for the owner of the car. I hope he has a safe trip. But twenty thumbs up for you Tim. A really great job.
Thank you. The customer was a little down but cheered up when I replaced his windshield wiper for free! Hope he gets a lot of use out of his Lincoln!
Thank you! Real world work!
Good job 👏
Great Work Tim. Thanks for showing us.
Aloha! Thanks for dropping by the shop
I'm always hanging out in the shop. I'm like that annoying fly when people use the bathroom.
we don't have flies here, just bears. And they aren't what I would call annoying, they just eat you.
I did this job once about 15 years ago so this is a great refresher. I remember having to get a big cheater pipe and a steel bar bolted to the flange to tighten that pinon nut to get the depth just right. I didnt see the depth set of the pinon on here? You have all proper tools so i was curious how it was done. That was the hardest part i remember.
Thank you very much i am about to work on 2005 Lincoln town car that was very helpful thanks again for your time
Great video really enjoyed watching it
You should always use brass punches when installing new bearing races.
... in Alaska sometimes bushfix comes into play 😊
hi Tim; have a few questions: my 2005 lincoln towncar has a kind of a steady clunk when the rear tires are off the ground when put in drive. i feel it when i put my hands on the pumpkin. but i doesn't have that same clunk when riding down the road. has more of a howling sound. changed the bearings and seals both sides in rear and still howling. also those 2 small gears fell out when i pulled that big pin out. does it matter if i got those 2 mixed up. those are the one you said would be hard to put them back in. Another thing is when you were putting that white grease to test the gap how do i really know if it's good enough. can you please help me out
Could you tell me the size of the bearing splitter you used on the carrier?
fantastic video. going to be doing the bearings on my 92 f150 with a 8.8 soon. is there a was to torque the pinion without a in/lb torque wrench or am i going to have to go buy one?
Great Video.. Thanks for the help..
Hey Doc, I know this video is old but I watched the whole thing and I really enjoyed it, thank you and God bless !!
Good job Tim !
Thank you buddy. IM glad I filmed this one. It was a fun job.
For future 8.8 jobs where you find yourself needing to remove both axle shafts, buy a length of metal pipe that spans the width of the axle housing and use it to knock the axle shaft bearings and seals together. It's a lot simpler AND QUICKER this way so you're not fiddling around with setting up a slide hammer. Anytime I have both axles out I knock my bearings and seals out together this way
How do you get it in from one side or the other if both axles are still in?
@@MrWontstopthefunk 🤔
Great video as always thank you
Thank you very informative ... I am thinking about having mine done very soon and making it posi.. trac
nice, ive put a few Eaton carriers in for the posi modification. They worked out well for Alaskan conditions and nice burnouts.
Don't forget the oil Slinger and the spacer by all means again thank you for the wonderful video
Awesome job there Tim. I don't see how anyone could botch that job after viewing this video.
Thanks! I am probably not the best instructor when it comes to diff work. I send a lot of it down the road to a specialty shop. Im sure someone is going to view this sooner or later and let us know how I did most of it the wrong way. haha
This chick I was runnin around with once had mustang & she loved that car. I noticed a axle seal leaking on one side of the rear end. She had been here all night & was ready to get going home but did say she wanted to come back that evening. She asked if I would look at her rear end then. I said she could come over & I'd be happy to look at her rear end. I would even be willing to look at her car as well if she liked! 😛
great job car dr
Nice video. But I have to confess I cringed watching you hammer in the pinion races by driving them in with a punch. 😅 Then I was a bit confused when you pulled out a race driver set to do the axle races. 🤔
great video, just changed diff oil today on my 2000 Lincoln towncar because the cover was leaking ,(silicone was leaking) and noticed my oil was a bit black with filing in it..is this bad??.
Awesome work........thanks
Thanks, it was a great project.
when would that step come into play, crushing the crush sleeve? thanks man your an awesome tech!
Wish I could afford a guy like yourself to do my Ford explosion rear differential...great job..I trust your work ..mine wines loud and shiny metallic flakes on magnet and all through the oil upon checking it last week....so so so disappointed.......188.000 miles
Change it yourself, it isn't that difficult.
You sure know how to keep a long boring job interesting.I like your funny sayings and jokes.
IM glad you do, some of my customers don't think its very funny. hahaha.
The Car Doctor Yea they wont be laughing when they get the bill that's for sure.
Nice Job.
Nicely done
WOW This Man is Amazing, I'am NOW A Fan, I Just SUBSCRIBED !!
Well done! Thanks.
Wow thank you for the Video! Good job and very awesome Video..
My 04 cvpi is making a clicking noise under low/med acceleration in 1st-2nd similar to the noise it made when you wiggled the whole gear around near the start. That mean I have bad bearings? It now has 171k on it and im not sure what has ever been done to it. Gonna try and change the oil and hope for the best.
Awesome Video Thanks so much!
Great video
Thank you
Ugh, sometimes those pins break. I never reuse them. Anyway that is what I was told!
good video learned a lot, thanks.
Great. Glad you watched. Take care!
an easier way to remove the axle bearings and seals when you have the carrier out is to use a long pipe about 1 inch diameter and put it through the end of the housing from one side until it contacts the bearing on the opposite side, wack it with a pony sledge and both pop right out, repeat for the other side..no fighting with the seals and no puller needed.
Good tip! I don’t do enough of this stuff to remember to use time saving tips like that. Happy New Years and thank you for watching my vids.
I'm changing my wheel bearings and I removed the diff cover but I think it's facing the wrong way, the bolt is on the back side and I can't spin mine like u did in this video, do I need to put it in neutral? Please help
Yes, needs to be in neutral.
Nice video. I learned a lot of information! Thanks Tim!!
Thanks, we are all learning stuff together on RUclips. I have changed the way I wrench even over the past year because of RUclips. Take care!
Also what size bearing splitter would I need? Or what do you use?
Love The Rear End Jokes
Very informative video , I’m getting ready to do my 2003 Lincoln , first time , I think I have to watch your video hundred times to get it right ,👍🏽 -- I need to know where is shop is and how much did it cost to that rear end job ?
you got this!
its probably cheaper to find someone on street corner for rear end job
Nicely done.
A little dab'll do ya.
I usually overdo the RTV part. Where a little is good a lot is better right? haha
Usually less is more except when you're dealing with mating surfaces on an automobile. If ya put too much on it'll squeeze out and be just right, not enough and ya gotta do it over and nobody wants to do it over, well mating surfaces on an automobile that is.
Know what I mean wink wink nudge nudge.
reminds me a song called "love is like oxygen"
That's actually a good song and like the definition of poison - too much of anything and ur gonna die.
Excellent, I enjoyed that. Two questions. Surely the axel was not that loose when you took out the ABS sensor? How did you tighten the pinion and crush the crush washer?
After removing the center pin in the differential carrier and removing the brake calipers, rotors and speed sensor the axle shaft will push in about 3/4" and allow for removing the inside c-clip that retains the shaft. the inner carrier pin does not allow the axle shaft to move in once it is installed. I used an impact on the pinion just a little at a time until I have proper preload. This may not be the recommended procedure but if your careful it works fine. If you go too tight then youll need to replace the crush sleeve and start over. Probably a few things that I didn't follow recommended procedure but I think it went out the door as a solid repair. Thanks for watching!
my pinion on my 04 f150 dosn't seem to come out of it's housing...
I banged it with a hammer but it still won't come off..
do I need to bang it till it comes off..??
Be sure to use a brass drift to force it out of the housing but yes youll need to use more force to remove it.
Change my axel today using your video. Went very smooth. Thank you!
Great Video. Very well detailed..just out of curiosity how much do you charge for a job like that? I believe I have the same issue with my 2004 Lincoln Aviator. I'm just trying to get ball park estimate.
parts kit + book...= $1200
You can get a Fel-Pro gasket for the differential cover - do you add RTV sealant in addition to the gasket, or gasket alone is sufficient? How much gear oil do these differentials take?
Nice work bud! I upgraded my rear end with a Eaton Detroit locker. It was a pain getting the back lash and pinion depth correct for a first time fix for me. What size hammer is that? 32 oz or 40oz
Thanks! The hammer is the big 40oz. Nice choice for Ford repairs.
Ya I bet. Nice ones. Or even that big sledge u have is needed.
Hey I change the wholes differential but know my car is soft what can be ???like
Did you have to pack the wheel axle bearings with grease before install
No, a light coating of gear lube is helpful. The diff fluid when filled will circulate through the bearings.
I did not see an “S” clip removed or installed. Isn’t that needed so the spider gears remain in place?
i just want to let you know i continue to really appreciate your videos i know it takes a lot of work to make them thanks
best video on this overhaul on YT....
Do you have part number for master rebuild kit? Is this something I can do at home?
Great video, did I miss the part about the crush sleeve? Maybe on this diff, it is not required? Please make comment. Thank you.
Nice vid
Where are you ? Nice video and knowledge hope you get many customers bro
Thanks, we are in Anchorage, AK
Good job car doc I'm hearing a pot and pan noise on a Malibu during accelerating it get loud any advice where to check first
Hey guys does it work to replace 04 differential with 98 ?? I mean my 98 differential has to be replaced
Anything is possible.
The Car Doctor thank you
I think it is called a oil slinger not a shim that goes between the rear pinion bearing and seal
Oh good call. I think you are correct. Thanks for the feedback. I was thinking it really wasn't shimming anything.
What r u cleaning it with
What were you using for your gear pattern? Did you ever use white lead? Now I'm showing my age.
I used to use Prussian Blue but don't remember the white product. I have to admit IM not the most experienced at differential repairs and just try to get them out the door without major problems. I just got to the point of no return on this one and decided I better plow forward and knock it out. I probably wouldn't choose to do them in the first place but it worked out ok. Take care.
hey awesome video! i didn't see you crush your crush sleeve though? you just set the pinion preload?
Its been a while but the crush sleeve is for setting and keeping pinion pre-load. Therefore it is "crushed" when setting preload. Thanks for asking and watching my vid!
How did you drop that spider gear pin, mine hits the pinion gear
Before removing the pin it is rotated to a position where it can be removed from the bottom of the case.
Very nice work Tim!! It's worth spending a few dollars more for the rebuild kit,being that he's going to Arizona that is. Great video and thanks again!!
Thanks, those cheep china parts can be a real problem. I have seen noisy bearings right out of the box. Good of you to stop by.
If i am changing the original carrier with an Eaton trutrac using the same ring and pinion gears, Do I need to mess with the pinion?
Just make sure the depth and lash are set properly I suppose.
@@ThecardoctorTV Thanks for the quick reply.
Does the Lincoln town car come with a ford 8.8 LSD ??
What's the torque spec on the carrier bolts?
Damn helpful video Sir! Thanks!
Thanks.
How much is a complete job like this for a 03 town car usually
Hey boss, is the same diferecials in all the cars
No, they made a 7" and an 8.8" diff with limit slip and non-limit slip.
Man if lived you closer I would get you to do my rear! Thank you for this Tim. I really enjoyed it and learned.
No way, you can do your own buddy. I know you know what your doing. I bet Eric could help if you got into a pinch. Good seeing you sir.
carrier- that's the word I lost below. Anyway, really great video. Thanks again for doing this.
Oh, and what's the torque on the 8(?) bolts from when taking the carrier apart? shop manual i assume.
You don't check backlash with dial indicator?
And he takes a pattern using white grease. I hope he could see it, because I sure couldn't.
How much did this cost all together parts and labor or how much would this cost now?
What's the torque on the 2 caps
Really, really great video, but is it ok to press on the outer race of the carrier bearing?
You should be very careful doing that because yes, they can crack.
It can make flat spots in the race or on the rollers is what I’ve been taught
Good educational video. thank you pal!
