In Salisbury axles, the carrier is integral with the axle housing. A removable cover at the rear, gives access to the final drive components.
The crown wheel is held in the carrier in a similar manner to the removable carrier type, but shims between the housing and the differential case bearings, allow the pre-load setting and backlash to be adjusted.
The pinion has a collapsible spacer for pre-loading, and depth-of-mesh shims for positioning with the crown wheel.
Hypoid bevel gears require special lubricants to withstand the high loads between the teeth.
In light vehicle applications, the wheel end of the axle shaft is normally supported by one bearing in the axle housing.
This is called a semi-floating arrangement: the axle shaft supports the vehicle mass, and transmits driving torque.
