Rear wheel bearing clunk

[vwdmc16]

I have had a similar issue with my left rear bearing, I've tried three different bearings and a few different Loctite sleeve locking compound. Even shimming metal between the bearing and housing. Nothing is really worked.

Ah bummer. Do you remember how long (miles) the bearing compound lasted before it failed? Or did it never work? I’m surprised the shims didn’t work, my understanding was that’s the ultimate solution assuming you could make the shims out of a hard enough steel. Something like aluminum wouldn’t cut it.

For what it’s worth these are the bearings I used: https://www.deloreango.com/us/rear-h...l-bearing.html
As I noted earlier these were significantly more difficult to install (I consider this a good thing) compared to how easy it was to remove the stock ones. I measured the new bearings to be 0.1mm larger than the stock. I wouldn’t be surprised if this is a significant factor to these bearings staying put (assuming they do!).

I had a similar clunk in the rear. When I did my frame off I found the shock bush was deteriorated and allowed for movement and that the hole for the shock had elongated, also it had worn about half way threw the threaded rod on the shock where it was rubbing on the frame. After a stainless frame and new shocks, no more clunk.

I'm all for this upgrade, but this has got to rate as one of the most expensive repairs of 2022!

Easy to check if that's your problem. You don't have to get a new frame, just have the hole repaired if it is.

If the hole for the shock is distorted the fix is to have a large washer welded over the hole. While you are at it check the other side too. Often when this happens it is because the shock is bad but it also happens when those rubber bushings go bad. If you do have to replace the shock "good Practice" is to do both front shocks.
