RV How-To: Trailer Axle Bearing Replacement Part 2
HTML-код
- Опубликовано: 5 окт 2024
- We'll share installing all of the new parts into our brake hubs for our Kodiak travel trailer. Once the hubs are installed onto the axles we'll share how to properly torque them and adjusting them to get the proper endplay or "pre-load" on the bearings. Using all new high quality parts, grease and care when installing everything is important to getting long life and reliability out of trailer brake hubs.
I have an Amazon affiliates page with the related tools and supplies I use for this work.

I've installed a blue million axle bearings and seals in my life and i've never seen anyone do as good a job as you just showed here. From cleanliness to the preload to the cap tool you've earning the title: Bearing Master. I wish every shade tree mechanic would watch this video to show the PROPER way to install bearings! Only thing I would have done different would to have had a brisket on the smoker while I was doing the job.
So glad I found this channel. Learning, cooking, adventuring, I can’t wait for the next adventure 👏👏👏
Excellent job Adam. Been doing this for years. I can guaranty you that your method is much better than ANY shop would ever do. Thanks for showing us the best way to do this.
I agree with everything you said. Never heard of any shop that packs trailer bearings, checking the backlash or even mentioning what that spec is. I've seen a lot of shops put the tire on and spin the hub while tightening the nut. I've done it myself on many anhydrous ammonia trailers. Kind of developed a feel for what was right. If you guessed wrong, the bearings went out. You get real good at it real fast just pack a few hundred bearings!
I have to admit that you are the first person I have ever seen torque the axel nut and use a dial indicator to check the backlash in the bearings, however you are NOT the first person I have ever seen that used a Cresent wrench as a hammer. :)
As a top certified technician for many yrs in a Ford Dealership I can guarantee that you did everything right here. I would never recommend that you let anyone touch your wheel bearings if you can do it yourself as no one will do it right. I'm very much a perfectionist like you and no I wouldn't have put a dial indicator on it as I have a good feel for it after doing if for 35 yrs or so but nothing wrong with that. I will say that when installing new bearings and races that you can take them down to zero backlash or even a very slight preload because when they wear in, there will probably be a few thou of backlash. Great Job Adam. Yes I use a bearing packer like that too, why would anyone want to do it the old school nasty way. Excellent job Man.
Thank you for taking the time to demonstrate the proper way to install wheel bearings on a trailer. i paid someone last time to do this job. that cost me a 200 dollar tire because the castle nut was too loose. Just glad I made it home. I am now replacing all the bearings myself. cant trust anybody to a good job these days.
Nice job man. So nice to see somebody press those bearing races in with a press when they have one, instead of beating them in with a hammer!
Just wanted to say thank you for such a thorough video. I was so intimidated to do this myself but finally decided to give it a shot. My trailer is a 2018 and the bearings had never been repacked. I have dual lippert 5200 lb axles. Bought everything I needed off Amazon for the most part and everything fit like a glove thankfully. I knocked out one side of the RV today, doing the other side tomorrow. Thanks again! - Roger from Smyrna, GA
Enjoyed your video. I'm in the middle of this job now and, I've done it before, but it's been a really long time and figured I could use a fresh review. I didn't see any problems with your work, and your assistant is very supportive too. I'm glad you mentioned at the very end that you had the brakes adjusted. Often you will have to loosen the brake shoes just to get the hubs off, and even if you don't there isn't a better time to readjust them while you're at it. Thanks.
I have been around and "helped" with a few bearing replacements. I say "I helped the real mechanic" because I didn't know really what I was doing. None I have ever seen took this much care with the job as you did. I'm impressed and learned some things today. Thanks.
Super job Abom! I cannot imagine that a professional trailer wheels place would do this level of high quality and detailed installation. Hopefully this is the end of all your trailer wheels and suspension troubles.
I'm with you on the "getting on the ground" work!! Been there and done that, really don't want to do it any more!! (retired now) Safe travels on your trip!!
Your Missus Rocks … positive and supportive!
Super tutorial & outstanding information! Replaced & repacked a few bearings over the years on an old vehicle but had never really known how to properly measure & set preload. I, too, just replaced our RV bearings with Timkens so I'm glad it was the right choice. Thanks so much for taking the time to show us the right way to do this.
I like the old fashion way of packing bearings, put a big glob of grease in the palm of your hand and force it up through the bearing. I appreciate this tool but seems like it was much quicker and just as effective to do by hand.
From my 45 years of pulling wrenches, you might want to set those bearings alittle bit tighter due to them not being a matched set and already seated to those races. But in about 100 miles they will be loose and need retightened
You guys make the perfect couple👍
Glad to see you showing the proper way to adjust wheel bearings. Great job! Dial indicator is the only way to know you have it correct. Other methods may work, but that is guesswork. Retired with 44 years in the field as a bearing and seal manufacturer rep, trainer and mechanic.
Always great to hear from someone who gives positive support to the work I share! 👍🏻
After watching you use a dial indicator in your other wheel maintenance video, I used mine when I repacked the ones on my camper. It makes me feel good that I’m actually in spec instead of guessing.
Great video and advice. I’m a retired machinist and just finished doing mine the same although I hat to back off a little for the retainer to clip on .004. Thank for spreading good advice.
Hello it’s Abby, be sure to check out Adams machining page, Abom79 if you haven’t! We love machinist around here!! ❤️
Great job! I have done this many times before and still I learned a few things.
You are very knowledgeable about the RV Excellence care that you provide. Wish l could travel like folks do. But l feel l seen a lot through your traveling
I normally add a little bit of grease on the seal to make sure the spring doesn’t pop off during installation. I’ve also had bad luck with the nut retainer clip coming loose and allowing the nut to start backing off. Do yourself a favour and check free play on the hub every once and awhile
Great tutorial Adam. As you enjoy your travels, it is much better to know that this was done correctly than wonder. Now you have no doubts.
For a machinest you make an excellent mechanic love your channel
I like to pull my boat and cargo trailer up against the curb and sit on the curb while doing this. And yeah, Roger on the peace of mind.
When you look at your bearing packer, you see there’s a grease nipple on the top. That’s how you feel the cavity full of fresh grease with a grease gun instead of a putty knife. It’s a little clean doing it with a grease gun
You may not be a mechanic, but you are a machinist. Plus you worked at a company that installed bearings for very expensive equipment. I'd like to believe you learned a thing or 2 while working there.
When I worked at a boat, boat engine, trailer repair shop in the 80's it was always fun to do a roadside service call for trailer bearings. People would often leave thier boattrailer parked in the yard for yrs, connect up and try to go fishing... only to get a mile or so down the road and the bearings burn up. Or even worse/extensive damage.
The procedure you have used is definitely correctly a little more retentive them most would use but there isn’t anything wrong with being so through
I got my mechanics cert. in about two years. I still pack my bearings the same way I did before I was trained. I gotta say you do a good job replacing and packing the new wheel bearings and races. I do it almost exactly the same way you do. When installing them I usually tighten the nut while I’m spinning the wheel until it bottoms out nice and snug. I back it off a little then snug it up a little. )Gotta be careful not to preload the bearing too much) the I put the castle over the nut and slide the cotter key in and bend the ends and curl them back over the nut. Sometimes I’ll put the bearing buddies on. Makes it easy to refill the grease. Some vehicles have preloaded bearing so ya gotta check the manual to get the specs. Pretty much the same as you Adam. Nice job done well.
Nice work Adam!
Very good!
I keep my bearing packer in an old large coffee can with plastic snap on lid... it keeps it squeaky clean, even over extended periods.
Also, a friend with a trailer told be he takes along an IR thermometer, and every time he stops runs around & does a quick check of his hubs... never seen him do it, but he says he's looking for uniformity. (For all I know this might be standard practice.)
Cool videos, Thanks!
That’s coffee can trick is great! I used to use them in the shop for many things. Nowadays I buy the little K-cups.
Thank you for sharing as always great video! Been a tech for 38 years! This is how it is done!!
brings back memories for me. you did the job just right
I’m happy to get my vehicle repair fix vicariously through you!
Living in an apartment in LA I don’t get to do much of this stuff these days.
Thanks for sharing, it’s like hanging out with friends building and fixing ish again, like back in the day.
First class job! No criticism at all.
Very good job, young man. I would recommend lubricating all the brake hardware whenever you have the drums off.
Retired ASE master tech.
I would think this is a weakness of the Kodiak company. They should have put these bearing on to start with !!!!! You have done many things to this unit.
The Gundoctor
Only thing I ever did different was I quit using bearing packers. They took up space and had to be carefully stored to keep the greasy suckers clean! Of course, getting the bearings properly packed is the important thing, however you choose to do it. Nice job!
Nice work Adam. Did you happen to note the date codes on those new tires? I was told when new tires are sold its a good idea to check the date codes to confirm how old they are when they are selling them to you. 6 months old maximum is to be considered a fair age for "new" tires and anything older should be rejected or negotiated by the customer. Many tire shops order tires and they are shipped from warehouses where they tend to sit until needed and some sit and sit before they are picked. I know one person who bought new tires and I checked the dates on them and they sold him tires that were 9 months old. Now a days, tire shops base much of their inspections on "age" of tires and will no longer offer the included rotation and balancing once tires reach 5 years in age. I had a conversation once with a well known tire sales warehouse and asked them where is the language in their "Lifetime" rotationa and balance policy that they will end that service based on age, not the tread depth. He couldn't show me anything but then said its a company policy not to service "old" tires then I asked, how fresh are the tires they sell to customers...1 month or 2 ? Told him they sold tires as much as a year old as new and he said "we would base that from the date of sale in that case".
Great job, dad always packed the bearings by hand, guessing that's how he was shown how when he worked on jets, and then he always wanted to shake my hand. Yes, I fell for it only to offend, got him a bearing packing tool, and I think it offended him. Wish he was around to shake his hand. Oh the good ol days of drum breaks. Great job .
You do everything with such care and attention. It's a breath of fresh air.
I had no idea of how to do this. You’re a genius!
No genius. We all learn what we know. 👍🏻
Great video. Informative and well presented.
Fluid film would help prevent the rust on the springs and frame
Great job. Love the quality work you do. Safe travels!!
When you have an issue with your electric brakes first thing you should check is those scotch lock electrical connectors since they will allow the wires to corrode. Best to replace them with heat shrink butt connectors. its probably fine for now just put it on your list of things to do / watch out for.
Good job on the hub bearings.
As always, excellent job…excellent video…excellent people! Thank you to both of you for sharing and for all of your hard work❤️
Very well done
Personally i would only use a manual press like a wheel press for the races, for feel. Also i never understood the point of spending money on bearing grease packers. Done by hand with a vinyl glove on, it’s as good as ever. Pack, turn, pack turn, pack turn, D U N done. And who the heck replaces dented dust caps? Adam does. 😂 👍🏻
If you want to keep your wife and your life happy, DO THE MAINTENANCE! Carry on sir!
Guess I need to make one of those grease cap installation tools. 👍
Adam, your doing it wrong :)
The boss is meant to do the work instead of giving you cheek and filming.
But Adam you did a great job
You did it wrong babe! Lol. Thanks for sharing, I need to do mine and watching your video I know I can do it. I am doing my leaf springs as well.
Great job Adam,! Being a machinist you can machine up some “distance pieces” that allow the nut to be done up tight and then used shims to setup the bearing clearance.This is the trick setup that many racers used as the distance piece adds to the axle stiffness so it flexes less.
Nice job. Only recommendation and I'm sure you did it but you should show cleaning the inner surface of the drum where the pads rub with brake parts cleaner to remove any grease that may have gotten on it.
I put Endurance tires on my Travel Trailer as well. It's been a really nice series!
Absolutely correct process. Great job.
Adam, you did good on this one. I used the same tools you had to pack the bearings also.
Adam, I respect your opinion on stuff like this, do you think the failure you had on the road of the left front was caused by the bearings failure or was the end play wrong or possibly both? Thanks for all the information you pack into every video! Jim
It’s hard to say. Could have been a combination of incorrectly installed hubs or bad bearings altogether.
This is the best video I’ve seen on bearing work , thanks ! . I’ve been doing it on my trailer for a few years , wish I had seen your video when I was learning. Was wondering if you adjusted your brakes also ……. Safe travels !
Advice-- keep a complete hub assembly as spare. When you have a spare you'll never need it. :)
Great job 👍🇺🇲
Perfect job 10\10 Adam . Like you machining nouse , I could adjust hub bearings by feel on hub end float or wheel rim rock or one hub nut flat back . See you last hub adjustment on your video, one nut flat back Adam😊
As they say in Italy "perfecto"... 🙂
Nice video I take it. The brake shoes are in good shape and didn’tneed to be replaced.
Across the desert??? Is that a hint about the big haul?
Check out our latest patio chat to learn more.
Since you own a grease gun it would not be a bad idea to fill the bearing packer through the built in zerk fitting , instead of the scraper, this would minimize the potential for air pockets.
Excellent job. I'm wondering if I could use a piece of pvc pipe in place of your own machined tool to install the dust caps ?
Hey Adam, just watched both videos on this. I've done this many times when I worked at a mechanics shop back in the 90's and early 2000's. I never knew to adjust backlash using a dial indicator. Where would I buy the dial indicator like you used and where do you find the specs from the bearing manufacturer? Y'all enjoy your trip. Looking forward to the videos.
Hey Russ, thanks for dropping by! The mag base and dial indicator is a pretty common tool that you can buy at any industrial tool supplier, but you should be able to find that same type of setup at Harbor Freight also. The inexpensive import dial indicators are great for general use stuff. When I worked at Motion I talked to Timken specialists often and had discussions about setting endplay. They actually provide the same info I mentioned on one of their RUclips videos as well. I’m sharing the info I learned from them. Hope that helps! 👍🏻
@@AbomAdventures Thanks Adam!
.005 would be a lot of clearance I think on those bearings. For ones that size I would want about .002”. I think .001” / inch of bearing diameter is a pretty good guide. The faster you run the looser they need to be because of more hub heat.
Precision preload, expected no less... 🙂
Im looking for a woman who looks at me the way Abby looks at Adam. You got it made bro.
I’m definitely proud to have such a loving, caring and supportive wife!
Adam, don’t you have to check brake drum ID to make sure they’re not too thin? Not familiar with trailer brakes, so maybe it doesn’t apply.
Great job. You’re hired.
I didn't see a parts list for the bearing kit do you mind sharing all 5 part numbers just bought a car trailer and have to do a bearing job thanks in advance
I would like to know where you found USA made timken bearings, when I did mine 2 years ago I couldn't find any USA made bearings, I bought FAG bearings that were made in Germany.
$100 a wheel instead of $35.
Instead of the (horizontal) vice, since you have a (vertical) press, why not use that to ensure even grease distribution?
Good job Adam! My camper doesn't have the brake adjusting dust covers, should I have them? I don't think my trailer inspectors don't replace my dust covers or torque my nuts like you do.
As the shoes weren't backed off from the drums the endplay measurements could be impared by the brake friction, and may have more availability for tightening...?
Just looks strange to have centre nut that loose.
Also im not criticising your work.
What's the point of first torquing to a defined value, and then backing off the nut? No critic, just curiosity....
You need to fix the brake wires!! Get rid of those connectors.
Where did you get that play bearing tool? What is the kind ?
What does Abby do for a profession/job?
If one of those fails, it's not because of the install. Cripes. Dial indicator!? I promise you, no "professional" uses a dial indicator to check endplay on a trailer bearing job.
2 things. The packer works better if you flip the bearing the other way, and you seriously need to fix the brake wiring on your trailer. Whoever put the axles in used cheesy crimp connectors and nothing about them is waterproof, plus zip tying to the leaf spring is not cool.. PS, Not criticizing!
Wonder if the grease tastes like cranberries ;)
Lippert and Dexter say 50 pound tork not 25 pound.
🇺🇸🇺🇸🇺🇸👍👍👍👀👀👀🥃🥃🥃🍻🍻🍻☕️☕️☕️🇺🇸🇺🇸🇺🇸
When I worked on my tractor trailer I used to have an old pair of coveralls that I'd wear and I never realized why my wife would want to hug me and sit on my lap when I wore them....mystery solved I guess.
that is not how you pack bearings... put some grease on your palm and get to work... my daddy would roll in his grave if he seen me use a grease packer...lol just kidding brother. great video.
***Won't grease on your brakes make your wheels spin better??**😁🤣😂😁🤣😂🤣😂
It keeps the brakes from overheating
@@dsma2023 🤣😂🤣😂
Wouldn't grease on the brake drums be a good thing?
You did it wrong!.......just kidding!
The ONLY thing you did wrong was the distinct lack of smoking meat and beer in the background.
