Hello; Those bearings were NTN bearings bought at BC Bearings in Nanaimo.

A heighbour has a VW golf that he uses to commute to work and back (60 miles each way). He replaces his rear wheel bearings yearly, claiming that he can feel them going. I changed them the first time, he has done it every year since. I thought it was unusual, but he doesn't mind, and he does have nearly 400,000 kms on it. Looking at the removed bearings you can definately see a lot of wear compared to the new ones. These are roller bearings not balls and are tensioned by the nut on the axle. I thought he was buying cheap bearings but he gets them from VW, so they are factory authorised, and they are quite expensive.
