Brake Rotor/Disc: Service and Repair
Installation
Front Hub And Rotor Assembly
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 and/or rear wheel bearings without first identifying the type of original wheel bearing lubricant. Usage of incompatible
bearing lubricants may result in premature lubricant breakdown.
1. If a new hub and rotor will be installed, remove the protective coating, any dirt or grease deposits with brake parts cleaner or degreaser.
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 and 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, and adjust the wheel bearing.
6. Install the retainer, new cotter pin, and grease cap.
7. Install the caliper.
