Remove the inner wheel bearing and clean all parts with solvent, inspecting for any damage. Replace any defective bearing races and use high-temperature front wheel bearing grease to pack the bearings.

To maintain front wheel bearings, it's crucial to periodically check them for issues, primarily when the vehicle is raised or if you encounter symptoms like noise, rolling resistance, or endplay while spinning the wheels. While the vehicle is securely supported on jackstands, check for any noticeable movement in the wheels on the spindle by moving them in and out. If there's movement, it's necessary to inspect and potentially repack or replace the bearings. Start by removing the wheel and disc brake caliper, then proceed to remove the front locking hub assemblies. Bend back the tabs on the lock washer, remove the outer locknut, lock washer, inner locknut, and thrust washer. To disengage the outer wheel bearing, pull the hub assembly out slightly and then push it back in. Afterward, remove the hub assembly from the spindle and carefully pry the seal out of the rear of the hub assembly. Thoroughly clean the old grease from the bearings, hub, and spindle using solvent, inspect the bearings and races for damage, and replace them if necessary. Use high-temperature front wheel bearing grease to pack the bearings and apply a thin coat of grease to specific spindle areas. Place the grease-packed inner bearing into the hub, install a new seal, and tap it into place. Carefully put the hub assembly back onto the spindle, install the thrust washer and inner locknut, tighten it while rotating the hub, and then back it off before retightening. Install the lock washer and tighten the outer locknut, ensuring proper bearing preload. Finish the installation by following the reverse order of removal, and don't forget to lightly grease the internal components of the manual locking hub assembly.
