I know of T3 Kombi to have 400+ and never even heard a murmur from the rear bearings.
I replaced the nsr today,I only did the both sides 2 or 3 years ago.I had a growl coming from that side,that changed pitch when braking,in and out of gear.
The inner felt a little gritty.Hard to test the outer.
Its got me thinking....
Faulty bearing?in-correct install?driving conditions?worn axle?worn bearing hub?in-correct off set????Surely there is other Kombi running around with different off-sets and their not changing rears bearings every couple of years.
Any one have any theories?
BTW the nut was tight.
