To remove the hub and bearing assembly from a vehicle, start by putting the vehicle in gear, applying the parking brake, and breaking loose the driveaxle/hub nut with a socket and large breaker bar. Then, loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and the driveaxle/hub nut. Next, unbolt the brake caliper and hang it out of the way with a piece of wire, and remove the brake disc. For models with four-wheel ABS, trace the electrical lead for the wheel speed sensor and unplug the electrical connector. Remove the hub assembly-to-steering knuckle bolts, as well as the brake disc shield and wheel speed sensor assembly. Tap the hub assembly from side-to-side to break it loose from the steering knuckle, and pull it off the end of the driveaxle. If the hub is stuck on the splines, use a puller to free it. To install the hub and bearing assembly, lubricate the driveaxle splines with multi-purpose grease and tighten all of the fasteners.

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands.

Slightly pull the hub/disc assembly out and push it back to facilitate the removal of the outer bearing. Subsequently, detach the hub/disc assembly from the spindle and use a screwdriver to pry out the seal from the rear of the hub, taking note of its installation.

The bearing puller can be found at tool stores and auto parts stores.

Subsequently, use high-temperature front wheel bearing grease to pack the bearings and apply a thin coat of grease to designated spindle areas. Add grease inboard of each bearing race inside the hub, forming a dam with your finger to contain excess grease.

Unbolt the brake caliper and hang it out of the way with a piece of wire.

After reinstalling the front wheel bearings, install the dust cap, replace the brake caliper, reattach the wheel, and check the bearings' condition by grasping the top and bottom of the tire.

A new oil seal should be installed.

A bearing puller is needed.

After removing the outer bearing, proceed to remove the inner wheel bearing, clean all components thoroughly with solvent, and meticulously inspect the bearings and races for damage.

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands.

The new bearing can be installed using a bearing installer or a piece of pipe against the outer bearing race.
