M37 Rear Hub Rebuild

Part numbers for the bearings and races:

Inner Bearing – Timken 28682
Outer Bearing – Timken 2984
Inner Bearing Race – Timken 28622
Outer Bearing Race – Timken 2924

Inner Seal – National 417485
Outer Seal – National 6077

Exploded view of the rear axle for reference.


I used a 2 jaw puller to get the inner seal out of the hub, it’s a lot easier than using a drift punch from the other side.  It also reduces the chances of damaging the bearing or race.

Indiana 225
