1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, wheel chocks.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Place wheel chocks behind the rear wheels to prevent movement.

Loosen the lug nuts using the lug wrench.
Remove the lug nuts completely and take the wheel off to access the hub assembly.

4. Inspect the Wheel Bearing

Check for any play in the wheel hub by rocking it back and forth.
Spin the hub to feel for smoothness; any roughness indicates a bad bearing.

5. Replace the Wheel Bearing (if necessary)

Tools Required: Socket set, bearing puller, grease, torque wrench.
Remove the brake caliper and rotor if they obstruct access to the wheel bearing.
Use a bearing puller to extract the old wheel bearing from the hub.
Clean the bearing housing and apply a suitable grease.
Install the new bearing, ensuring it is seated correctly.
Reassemble the rotor and caliper, and torque to manufacturer specifications.

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
