Differential Assembly Overview

Differential Assembly Overview

• Heat inner race/tapered roller bearing to approximately 100° C before installing.

• Always replace both taper roller bearings together as a set.

• Adjust differential => [ Differential, Adjusting ] Differential, Adjusting, when replacing tapered roller bearing, differential housing, transmission housing and clutch housing.
