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.
Before handling the bearings, there are a few things that you should remember to do and not to do.Remember to DO the following:
Do NOT do the following:
- Raise and 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.
- The hub and bearings are usually replaced as a unit. The hub and bearing carrier may, however, be disassembled and the bearings replaced as a set. Once the hub and bearing carrier have been separated, the bearings should not be reused.
- Pack the hub cavity and bearings with wheel bearing grease and 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) and install the cap and new cotter pin.
- Install the rotor, caliper and wheel.
