Rear Wheel Hub and Bearing Assembly
NOTE:
The rear ABS sensor is routed through the back of the rear backing plate and into the side of the wheel hub
and bearing assembly. It is necessary to remove the wheel hub and bearing assembly to remove the rear ABS
sensor.
REMOVAL
1. Remove the wheel and tire using power tool.
2. Remove the rear brake caliper, without disconnecting the hydraulic hose, using power tool. Reposition the
rear brake caliper aside using suitable wire. Refer to BR-36, "
Removal and Installation of Brake Caliper
and Disc Rotor".
NOTE:
• Do not depress the brake pedal while the brake caliper is removed.
3. Remove the rear disc rotor.
4. Remove the cotter pin, then remove the nut from the drive shaft using power tool.
• Discard the cotter pin, use a new one for installation.
5. Remove the drive shaft. Refer to RAX-10, "
Removal and Instal-
lation".
6. Remove the four wheel hub and bearing assembly bolts using power tool. • Discard the four wheel hub and bearing assembly bolts, use new ones for installation.

7. Pull out the wheel hub and bearing assembly for access to remove the rear ABS sensor from the wheel hub and bearing
assembly as shown.
• Inspect the ABS sensor O-ri ng, replace the ABS sensor
assembly if damaged.
• Clean the ABS sensor hole and mounting surface with a suit-
able brake cleaner and a clean lint-free shop rag. Be careful
that dirt and debris do not enter the axle bearing area.
• Apply a coat of suitable grease to the ABS sensor O-ring and
mounting hole.
CAUTION:
Do not pull on the ABS harness.
8. Remove the wheel hub and bearing assembly.
INSTALLATION
Installation is in the reverse order of removal.
• Apply grease 44003 7S000 to contact surface between wheel hub and drive shaft. Use sufficient grease to completely coat contact
area.
• Inspect the ABS sensor O-ring, replace the ABS sensor assembly
if damaged.
• Clean the ABS sensor hole and mounting surface with a suitable brake cleaner and a clean lint-free shop rag. Be careful that dirt
and debris do not enter the axle bearing area.
• Apply a coat of suitable grease to the ABS sensor O-ring and mounting hole.
• Use a new cotter pin for installation.
• Use new wheel hub and bearing assembly bolts for installation.

O P
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load. With brakes appllied, place A/T shift selector in drive position.
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
• Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
• If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis Ear: J-39570, Engine Ear and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
• removing the components in the area that you suspect the noise is coming from. Do not use too much force when removing clips and fasteners, otherwise clips and fastener can be broken
or lost during the repair, resulting in the creation of new noise.
• tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only tem-
porarily.
• feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
• placing a piece of paper between components that you suspect are causing the noise.
• looking for loose components and contact marks. Refer to RF-46, "
Generic Squeak and Rattle Troubleshooting".
REPAIR THE CAUSE
• If the cause is a loose component, tighten the component securely.
• If the cause is insufficient clearance between components:
- separate components by repositioning or loos ening and retightening the component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A Nissan Squeak and Rattle Kit (J-43980) is av ailable through your authorized Nissan Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
The following materials are contained in the Niss an Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.
