For reference, you will be able to get bearings and seals at a driveline or transmission shop for less than half dealer price with this info. These are standard metrics sizes, bring your old ones in to make sure if you like. One of each will do the rear hub.

This is actually a much more complete post.



Yes, I did search the old post last night and able to retrieve what I think are the bearing numbers & kit numbers. Now was the time for purchase

The research I did turned up this

Front Bearing Wheel Kits

MSR 41-3615 Retail 23.00

Pivot 41-6690 Retail 30.00 PWFWK-Y07-421

All Balls 41-6904 Bearing R $8.85
