REMOVAL, PACKING AND INSTALLATION
See Figure 1
Only 1987-90 models have hubs which contain tapered roller bearings that can be serviced or replaced as necessary. Hubs which contain ball bearings cannot be serviced, so the complete unit must be replaced if found defective.
Before handling the bearings, there are a few things that you should remember to do and not to do:Remember to DO the following:
- Raise and safely support the front end on jackstands.
- Remove the wheel.
- Dismount the caliper and suspend it out of the way.
- Remove the rotor.
- Remove the hub nut pin, cap and nut.
- Remove the hub. Although the hub and bearings are usually replaced as a unit, the hub and bearing carrier may be disassembled and the bearings replaced as a set. In this case, they must first be separated with an arbor or hydraulic press. Once the hub and bearing carrier have been separated, the bearings should not be reused.
Sodium-based grease is not compatible with lithium-based grease. Read the package labels and be careful not to mix the two types. If there is any doubt as to the type of grease used, completely clean the old grease from the bearing and hub before replacing.
- Pack the hub cavity and bearings with wheel bearing grease, then install the hub on the axle shaft. If the carrier was separated from the hub, make sure you install a new carrier seal and inner bearing seal.
- Install the hub washer and nut. Torque the nut to 175 ft. lbs. (237 Nm), then install the cap and a new cotter pin.
- Install the rotor, caliper and wheel.
