Pierre, yes I did take them to the local autoparts store and they had everything I needed except I'd had to change brands and I just wanted to stay with the timken brand because that's what Vans had sent with the kit. I'm sure any of the other would have been fine too... I guess I'm a little OCD.
Alton, if you ever need bearings, the numbers you'll need are stamped on the side of both the cone bearing and the cup race.
Gasman, actually you have to purchase the bearing halves separate. The cone or "male" half has the rollers and the cup or "female" half is the race which is pressed in.
