Wheel bearing won’t fit?

**rar110** · 22nd August 2019, 07:59 PM

I’ve had a worn front wheel bearing or bearing track which was causing wheel wobble in my 1989 110. A wheel check confirmed movement after jacking up the wheel.

So removed the hub an replaced both bearings and tracks with RTC3429. But the bearing won’t fit over the stub axle.

I’m doing some work fitting old hubs on a new rear axle and they don’t fit the rear axle or this front axle.

Any suggestions? Thanks

Very common, the new bearing will be EXACTLY the right ID. However a worn stub will have a lip, of even some ovality if run with a worn bearing set for long.

Thanks JC.
Is the solution new stub axles?

Yep that.

try heating the bearings up in the oven to about 120-130 Deg C.

but ideally you want to inspect and rectify the stubs.

I wouldn’t be heating up to fit (good for roadside fix)......as it might cause issue setting the bearing up and or removal later.

I assume you have quality bearing.

I’d go with new stubs.

Yes they are Timken bearings.

I have a spare vehicle. I might try the stub axles off that first. Just so I can finish this on the weekend.

You could use emery paper and clean up the stub if its not too bad.

Or give it a light file,but it will still never be right,a new bearing will just wear it more over time.
Just a band aid effort,replacing the stub axle is the only way to sort it for good.

Thanks for the replies. I would like to sort it this weekend so will have a go at taking a stub off another housing. Will check if new bearing fits first.

Unless the stub has hosted a total bearing failure, I've always gotten away with a strip of some emery cloth and some elbow grease.
It also helps to trial fit the bearings prior to fitting to hub and getting stuck half on etc
