Wheel Hub: Description and Operation

DESCRIPTION





The wheel bearing (5) and hub (3) are pressed into the knuckle (1). The wheel bearing is secured in place using a snap ring.





One side of the wheel bearing has an integrated magnetic encoder ring for wheel speed sensor usage as equipped. It is important that the wheel speed sensor magnetic encoder ring (dark band) (3) be positioned to the inside of the knuckle or the wheel speed sensor will not operate correctly.

The wheel bearing is a Unit 1 type cartridge bearing that requires no maintenance. The wheel bearing can be serviced separately from the hub.

The hub supports the driveline halfshaft outer constant velocity (C/V) joint. Each is splined and meshes in the center of the hub. The outer C/V joint is retained to the hub using a nut. The nut is locked to the outer C/V stub shaft using a cotter pin.

The hub has five studs pressed into its flange.
