Wheel Hub: Service and Repair
Installation
CAUTION: Wheel bearing lubricant is a lithium-base grease. Sodium-base grease is not compatible with lithium-base grease and should not be
intermixed. Therefore, do not lubricate front wheel bearings without first identifying the type of original wheel bearing lubricant. Usage of incompatible
bearing lubricants may result in premature lubricant breakdown.
Installing Bearing Cups (Typical)
1. If inner or outer bearing cups were removed, install replacement inner and outer bearing cups in the hub with the appropriate bearing cup replacer
tool. Be sure to seat the cups properly in the hub. The cups will be properly seated when they are fully bottomed. Replace grease retainers. Polish
grease retainer journal on spindle with 400 grit sandpaper. Clean with clean cloth.
2. Pack the inside of the hub with lithium-base grease or equivalent. Fill the hub until the grease is flush with the inside diameters of both bearing
cups. Pack the bearing cones and rollers with wheel bearing grease. Use a bearing packer for this operation. If a packer is not available, work as
much lubricant as possible between the rollers and cages. Lubricate the cone surfaces with grease.
Installing Grease Seal (Typical)
3. Place the inner bearing cone and roller in the inner cup and install the new grease seal. Be sure that the seal is fully seated.
4. Install the hub/rotor on the wheel spindle. Keep the hub centered on the spindle to prevent damage to the grease retainer or the spindle threads.
5. Install the outer bearing cone and roller and the flat washer on the spindle, then install the adjusting nut.
6. Tighten adjusting nut to 23-34 Nm (17-25 ft lb) while turning the rotor in the opposite direction to seat the bearings.
7. Loosen the adjusting nut one half turn.
8. Retighten the nut to 2.0-2.3 Nm (18-20 in lb) using a torque wrench.
9. Place the retainer on the adjusting nut. The castellations on the retainer must be aligned with the cotter pin hole in the spindle.
