How to check and repack your wheel bearings

When should the wheel bearings be repacked with new grease? The number of miles range from 20,000 to 40,000 depending on the type of driving that you do,
where you live. If you drive long distances at high speeds or drive on wet roads, repacking should be more regular than in town driving in mild climates.

After you have removed the wheel bearings, wash them in solvent with a mild bristle brush. Inspect for binding, wear, scratches, heat discoloration, and bent or damaged cages by slowly rotating the bearings slowly. Replace if you see any of these. Dry bearings with low pressure compressed air then wrap them in a cloth towel that is clean and lint free.

Clean the hub area of drum and clean the spindle of vehicle you are doing the repack on.
Using a pressure packer in better than doing the pack with the palm of your hand. Make sure that the lubricant is completely worked through the bearing cage and rollers. Add a small amount of grease to the spindle and bearing races. Always install new grease seals.
