Wheel Bearing Replacement Semi Trailer

Well in that case, keep a close eye. And if s-cam bushings are worn out. Might have to adjust more frequently. Running mountains maybe every other day.

 

It might not be what you want to hear, but if that's an older trailer and the history of it is unknown, I wouldn't move it any farther then from the yard to the garage to work on it.

Not telling you what to do and it's just my opinion but when you buy something that is completely and totally unknown and you see something like that that's like the slack adjuster probably hasn't been greased in I'm guessing years... I myself no way would I run that without working on it first.

As was said I would check the s cams to see if they're good..

Then it's all brand new best quality that you can buy air Chambers slack adjusters and most likely seeing what you have there you need s cams and bushings. If needed all new brake lining and drums definitely. Check all Airlines for problems. If there are airbags and shocks on there I would replace them before I move that one inch. And I would replace all wheel seals and make sure the bearings are good and adjust them properly.

Why do all that work and spend that much money?

Because you'll pull two loads and blow out a wheel seal. Then you fix it and get pulled into a scale. And he's going to tell you you have a bad slack adjuster. Then you'll fix that and go down the road and an air chamber will blow out. Then you'll fix that go down the road and get pulled in by DOT again and they'll tell you you have another bad slack adjuster. Then you'll go down the road and use the truck for a while and another wheel seal will blow out. Then you'll fix that and another air chamber will blow out. Then you'll fix that and all the sudden on another wheel your bearings are bad and your hubs are ready to fall off and maybe you need to call the axle surgeon.

My point is that for a couple of days work maybe and a little bit of money you'll be able to use that trailer every day for the next however many years and never think twice about it.

You actually lose more money running around in circles trying to put Band-Aids on things than you do to just get into it one time and fix it and never look back.

I'm not trying to fault you or give you a hard time at all. Just my opinion and the way that I do things. But in this business the one thing that truly will make you money is dependability and something old and used should not be put into service until you know it's 100% ready and dependable.

 

They still offer matched set, only way I buy them. If you want a really good set of Timken, look into the 454 series of bearings. Specs on them is half the industry standard. 454-Series™ Tapered Roller Bearings for Commercial Vehicles - The Timken Company
