- Safety precautions:
- Park the vehicle on a level surface and engage the parking brake.
- Chock the wheels on the opposite side of the vehicle for safety.
- Allow the brakes to cool before starting any work.
- Remove the wheel:
- Use a socket wrench to loosen the lug nuts on the affected wheel.
- Carefully lift the vehicle with a floor jack and place jack stands under designated jack points.
- Remove the lug nuts and take off the wheel.
- Disassemble the brake caliper:
- Remove the caliper bolts with a socket wrench.
- Gently lift the caliper off the rotor and secure it out of the way.
- Remove the rotor:
- Remove the rotor mounting bolts and lift the rotor off the hub.
- Extract the old bearing:
- Using a hammer and chisel, carefully tap the bearing out of the hub.
- Clean the hub thoroughly with brake cleaner to remove any debris.
- Install the new bearing:
- Apply a thin layer of anti-seize lubricant to the new bearing.
- Carefully press the new bearing into the hub using a bearing press or a large socket as a drift.
- Ensure the bearing is fully seated and flush with the hub.
- Reassemble the rotor and brake caliper:
- Place the rotor back on the hub and tighten the mounting bolts.
- Reinstall the brake caliper and bolts.
- Reinstall the wheel:
- Lift the wheel onto the hub and tighten the lug nuts by hand.
- Lower the vehicle and torque the lug nuts to the specified specification.
- Inspection and testing:
