Rear Drive Axle/Differential - Rear Drive Axle and Differential
Description and Operation
Description
The welded steel rear axle casing houses a separate spiral bevel type differential unit, which is off set to the right of the
vehicle centre line. The differential unit drives the rear wheels via the axle shafts and fully floating hubs which are
mounted on tapered roller bearings.
Lubrication
The differential is lubricated with oil and the hub bearings with grease.
The hub bearings are fitted with inner and outer seals. The outer seals prevent the differential oil mixing with the hub
grease and the inner seals prevent dirt ingress into the hub.
Ventilation
Ventilation of the hub bearings is through the outer oil seals and the differential ventilation pipe, which terminates at a
high level.
