HUB / BEARING
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 mag-
netic 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.
DIAGNOSIS AND TESTING
WHEEL BEARING AND HUB
NOTE: The wheel bearing is designed to last for the life of the vehicle and requires no type of periodic
maintenance.
The following procedure may be used for diagnosing the condition of the wheel bearing and hub.
1. Remove the wheel and tire assembly, disc brake caliper and brake rotor. (Refer to 5 - BRAKES/HYDRAULIC/
MECHANICAL/ROTORS - REMOVAL)
2. Rotate the wheel hub checking for resistance or roughness.

Any roughness or resistance to rotation may indicate dirt intrusion or a failed hub bearing. If the bearing exhibits any
of these conditions, the hub bearing will require replacement. Do not attempt to disassemble the bearing for repair.
If the wheel bearing is disassembled for any reason, it must be replaced.
Damaged bearing seals and the resulting excessive grease loss may also require bearing replacement. Moderate
grease weeping from the bearing is considered normal and should not require replacement of the wheel bearing.
To diagnose a bent hub, measure hub runout. (Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/ROTORS - DIAG-
NOSIS AND TESTING)
REMOVAL
NOTE: The removal and installation of the wheel bearing and hub from the knuckle is only to be done with
the knuckle removed from the vehicle.
1. Remove the steering knuckle from the vehicle. (Refer to 2 - SUSPENSION/FRONT/KNUCKLE - REMOVAL)
2. Position the locator block (2) for Fixture, Special
Tool 9712, as follows:
a. For left side knuckles, place the locator block
(2) to the left side (4) on the Fixture. The side
of the locator block with the angle cut goes
downward,
toward
the
Fixture.
Install
the
mounting screws and tighten them to approxi-
mately 54 N·m (40 ft. lbs.).
b. For right side knuckles, place the locator block
(2) to the right side (3) on the Fixture. The side
of the locator block with the angle cut goes
downward,
toward
the
Fixture.
Install
the
mounting screws and tighten them to approxi-
mately 54 N·m (40 ft. lbs.).
