REAR AXLE HUB ASSEMBLY

REMOVAL AND INSTALLATION

M1271002000347

CAUTION

•

Care must be taken not to scratch or damage the teeth of the ABS rotor. The ABS rotor must never
be dropped. If the teeth of the ABS rotor are chipped, resulting in a deformation of the ABS rotor,
it will not be able to accurately detect the wheel rotation speed, and the system will not function
normally.

•

The rear hub assembly should not be dismantled. When removing the rear hub assembly, the
wheel bearing inner race may be left at the spindle side. In this case, always replace the rear hub
assembly, otherwise the hub will damage the oil seal, causing oil leaks or excessive play.

REMOVAL SERVICE POINTS
