Rear bearings keep failing

[Jimandcharlotte]

Hi, looking for some advice to help keep my t25 on 4 wheels!

The bearings on the rear nearside wheel have failed on me 3 times in the last month. First ended with the whole wheel coming off on the M1 (I'd decided the clanking noise was just louder than normal cos we had the windows down.

Got it all fixed up with new hub, bearings and split axle by a good VW specialist.

But after less than 200 miles, noise was back and on inspection the bearings were knackered again and wheel was about to fail. The was while in Spain so stretched the language skills a bit.

Garage fitted new bearings (after 6 day wait for them to arrive) and all seemed good, but 150 miles later and the same clanking noise on each rotation when drive is engaged is back. Currently sat waiting for friendly RAC man to get us back home.

Anyone got any ideas what might be root cause and how to fix this good and proper?

Are you sure that it is the bearings?
Have you checked the CV joints?

Have the half shaft and hub carrier been replaced??

The other question is has it been torqued up properly... 280ft/lbs is pretty darn tight...

The other thing that needs checking is that the bearing housing is within tolerance and not elliptical...

.

Even tighter if you tighten to the correct torque 500Nm

I thought it was 450Nm/330 lb.ft.

Thanks for the suggestions. The half shaft and hub Carrier have both been replaced (after wheel coming off incident) so it's defo something else creating the conditions for other things to keep failing. Will look into cv joints etc.

Interesting that the T3 hub torque is higher than a T2...
