Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery cable for safety.

2. Lift Vehicle

Use a jack to lift the front or rear end of the vehicle based on the suspected wheel bearing issue.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts from the wheel.
Take off the wheel and set it aside.

4. Inspect and Remove Brake Components

Remove the brake caliper by unbolting it from the bracket (use a socket set).
Hang the caliper with a wire to avoid stress on the brake line.
Remove the brake rotor by unbolting it from the hub assembly if necessary.

5. Remove Hub Assembly

Remove any retaining clips or bolts securing the hub assembly.
Use a hub puller if necessary to detach the hub from the steering knuckle.
Inspect the bearings for any signs of damage or excessive play.

6. Install New Wheel Bearings

If replacing, press new wheel bearings into the hub assembly using a bearing press.
Reinstall the hub assembly onto the steering knuckle and secure with bolts (torque to manufacturer specifications).

7. Reassemble Components

Reattach the brake rotor and caliper to their respective positions.
Reinstall the wheel and hand-tighten the lug nuts.

8. Lower Vehicle

Carefully lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
