To check the wheel bearings for basic problems, jack up each wheel to clear the ground. Hold the wheel and shake it to check the bearings for any play. Also rotate the wheel to check for any roughness. If any play is felt or there is noticeable roughness, the bearing may have to be replaced. Adjust the bearing; then, if play is still present, replace the bearing.
Over tightening the spindle nuts will cause excessive bearing friction and will result in rough wheel rotation and eventual bearing failure. Therefore, follow the procedures given in Suspension & Steering exactly, using the proper procedures and tools.
REMOVAL PACKING AND INSTALLATION
See Figures 1, 2, 3, 4, 5 and 6
- Slightly loosen the rear wheel lug nuts. Raise and support the rear of the vehicle.
- Release the parking brake. Remove the rear wheel assembly.
- Remove the rear wheel grease cap, the cotter pin, the spindle nut retainer, the spindle nut, the thrust washer and the outer wheel bearing.
- Pull the brake drum from the wheel spindle.
- Using a hammer and a drift punch, drive the outer bearing race from the hub.
When removing the bearing races, use a criss-cross pattern to avoid cocking the race in the hub bore.
- Turn the hub over and drive the inner bearing race and grease seal from the hub; discard the grease seal.
- Using solvent, clean the bearings, races and the hub. Using compressed air, blow dry the components.
- Using the Bearing Driver tool No. 07949-6110000, 07749-0010000 or equivalent, and the Driver Attachment tool No. 07946-6920100 or equivalent, drive the bearing races into the hub until they seat against the shoulders.
- Using Multipurpose grease, pack the wheel hub and the wheel bearings, also, lightly coat the lips of the grease seal. Install the inner bearing into the hub.
- Using a mallet, tap the grease seal (using a criss-cross method) into the rear of the hub until it is flush with it.
To install the hub, reverse the removal procedures. To adjust the spindle nut, perform the following procedures:
- Rotate the brake drum and torque the spindle nut to 18 ft. lbs.
- Loosen the spindle nut and retorque to 3 ft. lbs.
- Install the spindle nut retainer and align a slot with the hole in the spindle.
If the cotter pin holes do not align, tighten the nut slightly until they do.
- Using a new cotter pin, install it through the spindle nut retainer.
- To complete the installation, fill the grease cap with multi-purpose grease and reverse the removal procedures.
