Spindle: Description and Operation

Description
The rear wheels and brake drums are supported on the opposed tapered roller bearings. The bearing inner races ride on a spindle attached to the torsion beam.

The outer bearing races are pressed into a hub that is an integral part of the brake drum. Contamination of the bearing lubricant is prevented by a seal on the inboard side and a grease cap on the outboard side.

The brake drum-hub bearing assembly is attached to the spindle with a nut.

The nut and washer are used to hold the bearings and hub in position on the spindle and set the bearing preload.
