Step-by-Step Guide
1. Remove the Wheel
Use the socket wrench to loosen the lug nuts on the affected wheel but do not remove them completely. Jack up the vehicle and secure it on jack stands. Remove the lug nuts and detach the wheel.
2. Dismantle the Brake Caliper
Unbolt the brake caliper mounting bolts and carefully lift it off the rotor. Suspend it using a wire or bungee cord to prevent damage to the brake line.
3. Remove the Brake Rotor
Slide the brake rotor off the wheel hub. If it’s stuck, gently tap it with a hammer and chisel.
4. Extract the Axle Nut
Locate the axle nut in the center of the wheel hub. Use a socket wrench to loosen it but do not remove it completely.
5. Detach the Wheel Hub
Use an impact wrench or a heavy-duty socket wrench to remove the axle nut. Slide the wheel hub off the axle.
6. Replace the Wheel Bearing
Press the old wheel bearing out of the hub using a bearing removal tool or a socket and hammer. Clean the hub and apply grease to the new bearing. Carefully press the new bearing into place.
7. Reassemble the Components
Slide the wheel hub back onto the axle and tighten the axle nut to the specified torque. Replace the brake rotor and brake caliper. Tighten the caliper mounting bolts and reconnect the brake line.
8. Mount the Wheel
Place the wheel on the hub and tighten the lug nuts hand-tight. Lower the vehicle and fully tighten the lug nuts using a torque wrench.
Troubleshooting Tips
- If the wheel bearing is particularly stubborn, apply penetrating oil to the axle nut and let it sit for a few minutes before attempting to remove it.
- If the new wheel bearing doesn’t fit snugly into the hub, use a seal driver to gently tap it into place.
- If you encounter any unusual noises or vibrations after replacing the wheel bearing, have the vehicle inspected by a mechanic to ensure proper installation.
