HUB AND BEARING
DESCRIPTION
The rear wheel bearing and wheel hub of this vehicle
are a one piece sealed unit or hub and bearing unit
type assembly. The hub and bearing (1) is mounted to
the center of the knuckle using 4 bolts. It has five
wheel mounting studs (2) on the hub flange.
The center of the hub and bearing is splined to match
the axle half shaft.
The wheel mounting studs used to mount the tire and
wheel to the vehicle are the only replaceable compo-
nents of the hub and bearing. Otherwise, the hub and
bearing is serviced only as a complete assembly.
DIAGNOSIS AND TESTING
HUB AND BEARING
NOTE: The hub and bearing is designed for the life of the vehicle and should require no maintenance.
With wheel and brake rotor removed, rotate flanged outer ring of hub. Excessive roughness, lateral play or resis-
tance to rotation may indicate dirt intrusion or bearing failure. If the rear wheel bearings exhibit these conditions
during inspection, the hub and bearing assembly should be replaced.
Damaged bearing seals and resulting excessive grease loss may also require bearing replacement. Moderate
grease loss from bearing is considered normal and should not require replacement of the hub and bearing assem-
bly.
REMOVAL
HUB AND BEARING
1. Raise and support vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCEDURE)

2. Remove wheel mounting nuts (3), then tire and
wheel assembly (1).
3. While a helper applies brakes to keep hub from
rotating, remove hub nut (1) from the half shaft (2).
NOTE: In some cases, it may be necessary to
retract caliper piston in its bore a small amount in
order to provide sufficient clearance between
shoes and rotor to easily remove caliper from
knuckle. This can usually be accomplished before
guide pin bolts are removed, by grasping rear of
caliper and pulling outward working with guide
pins, thus retracting piston. Never push on piston
directly as it may get damaged.
4. Remove two bolts (1) securing disc brake caliper
adapter (3) to knuckle (2).
5. Remove disc brake caliper and adapter (3) from
knuckle as an assembly. Hang assembly out of
way using wire or a bungee cord. Use care not to
overextend brake hose when doing this.

6. Remove any clips (2) retaining brake rotor (3) to
wheel mounting studs.
7. Slide brake rotor (3) off hub and bearing (1).
8. Loosen each hub and bearing mounting bolt (2) a
turn or two at a time while pulling outward on hub
and bearing to avoid bolt contact with half shaft
outer joint. Once removed from threads in hub and
bearing (but not knuckle), allow bolts to stay in and
protrude through knuckle and brake support plate
to keep brake support plate in place when hub and
bearing is removed.
9. Slide hub and bearing off knuckle and half shaft.
