Re: How to replace rear wheel hub
Sodium based grease is not compatible with lithium based grease. Do not lubricate the wheel bearings without first thoroughly cleaning all old grease from the bearing. Use of incompatible bearing lubricants could result in premature lubricant breakdown.

Raise and support the vehicle safely.
-
Remove the wheels.
-
Remove the brake drum or brake disc.

-
Remove the cotter pin retainer, adjusting nut and flatwasher from the rear wheel spindle. Discard the cotter pin.

Clean the inner and outer bearing cups with solvent. Inspect the bearing cups for scratches, pits, excessive wear and other damage. If the bearing cups are worn or damaged, remove them using a Bearing Cup Puller (T77F-1102A) or equivalent.
To install:
-
Throughly clean old grease from the surrounding surfaces. If a new hub assembly is being installed, remove the protective coating using degreaser.
-
If the inner or outer bearing cups were removed, install replacement cups using Bearing Cup Replacer (T73-1202-A) or equivalent. Seat the cups properly in the hub.
If a bearing packer is not available, work as much grease as possible between the rollers and cages. Grease the cone surfaces.
-
Using a bearing packer, pack the bearing cone and roller assemblies with a premium bearing grease.
-
Place inner bearing cone and roller assembly in the inner cup. A light film of grease should be included between the lips of the new grease retainer.
-
Install the retainer with Hub Seal Replacer (T83T-1175-B) or equivalent. Be sure the retainer is properly seated.
Keep the hub centered on the spindle to prevent damage to the retainer and spindle threads.
