    Hello, I had a wheel seal go out on my semi trailer. The bearings didn't look too bad but it was a major seal leak so I decided to replace the bearings.

    I decided to not replace the race when I installed the new bearings and now have the hub already installed. but now I'm reading that you should always replace the race when doing new bearings.

    Is it okay to replace new bearings with an old race? or should I tear it all down again and start over?

    Bearing and race are to be changed as a set.

    What James said - but if you think those bearings were ok / it’ll be fine. Monitor the temps with an IR gun on a loaded trailer

    That’s what I was hoping. It would be ideal to have replaced the races. But it’s already assembled now so hoping it won’t cause me an issue. I’m losing hundreds everyday from having my truck down. So maybe I will run on it and fix it when work slows down. As long as it’s safe. The races didn’t have any visible damage.

    If I start over then I'm back to the parts store to get a new wheel seal.

    I can’t find anyone to work on my truck around here. so I got to do my first hub seal replacement that turned into a brake job too.

    I've done more than a few new bearings without replacing the races. I wouldn't be to concerned, just keep an eye on it for awhile

    So are you willing to chance it over the cost of a seal? When your at home its maintenance. When your on the road, its a breakdown. Which cost more.

    I'm not broke down in my yard or garage. Price of seal is cheap compaired to a wheel end failure, tow, damage to someone else's vehicle or family, axle surgeon. Cheaper to fix correctly at home everytime.

    But I'm not a gambler. Lord knows enough bad stuff happens out of are control.

    That lazy chicken sheet repair work. You should not be allowed to own tools.

    only good news is that I’m 100% local. I should have some down time coming. But in middle of a big job when that seal let go. I get it… do it right the first time.

    but you really think that thing is a risk to fly off the truck? I guess if you don’t pay attention to it.

    You will have shiny little metal in the gear oils as the old race eats into the new; bearings and gets into rear end?

    Won't happen in first 5 miles. But it will eventually. Old bearing, old races. Or new bearings, new races. Only option.
