#### ADJUSTMENT

##### Rear Wheel Drive

NOTE: Before adjustment clean all parts. Apply wheel bearing grease sparingly to the threaded portion of spindle and contact surface between lock washer and outer wheel bearing.

1. Raise and support the vehicle safely, remove the front wheels and the brake caliper assemblies.
2. Torque wheel bearing lock nut to 18–22 ft. lbs.

   NOTE: On the 1989–92 240SX model, the wheel bearing lock nut torque is 108–159 ft. lbs. On this model make sure that the wheel bearing is properly seated and then just torque it to the specification. There is just one wheel bearing and no adjusting cap on this model, just use a new cotter pin after the torque specification is reached.

3. Turn the wheel hub several times in both directions to seat wheel bearing correctly.
4. Again tighten wheel bearing nut to specification 18–22 ft. lbs.
5. Loosen lock nut approximately 60°. Install adjusting cap and align groove of nut with hole in spindle. If alignment cannot be obtained, change position of adjusting cap. Also, if alignment cannot be obtained, loosen lock nut slightly but not more than 15°.

   NOTE: If possible measure the wheel bearing preload and axial play. Repeat above procedures until correct starting torque is obtained. Refer to the illustration.

6. Spread the cotter pin and install hub cap with a new O-ring.
7. Install caliper assemblies and front wheels.
