Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools and parts.
Ensure the vehicle is cool before starting work.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which wheel bearings are being inspected.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Remove the lug nuts using a socket wrench.
Take off the wheel to access the brake assembly and rotor.

4. Inspect and Remove the Wheel Bearing

If necessary, remove the brake caliper by unbolting it and securing it out of the way.
Remove the brake rotor (if applicable) by unbolting it from the hub.
Use a bearing puller or appropriate tools to extract the wheel bearing from the hub assembly.

5. Install New Wheel Bearing

Clean the bearing housing thoroughly with a brake cleaner.
Apply grease to the new wheel bearing, ensuring it is well-lubricated.
Press or tap the new bearing into the hub assembly, ensuring it is seated correctly.

6. Reassemble Components

Reinstall the brake rotor and caliper.
Place the wheel back on the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specified value (typically around 80-100 lb-ft).
