Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Using a jack, lift the vehicle from the designated lifting points.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Remove the Wheel

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

4. Inspect and Test Wheel Bearing

Visual Inspection: Check the bearing for any visible damage or excessive grease leakage.
Spin Test: Rotate the hub assembly by hand. Listen for grinding noises or roughness.
Play Test: Grasp the hub at 12 o'clock and 6 o'clock positions and rock it back and forth. Any noticeable movement indicates a worn bearing.

5. Replace Wheel Bearing (if necessary)

Remove Hub Assembly: If the bearing is faulty, remove the brake caliper and rotor to access the hub assembly.
Disconnect: Remove any retaining clips or bolts securing the bearing to the hub.
Press Out Old Bearing: Use a bearing puller to remove the faulty bearing from the hub.
Install New Bearing: Press in the new bearing using a suitable press tool or by tapping it in with a mallet (ensure it is aligned).
Reassemble: Reinstall the hub assembly, brake rotor, and caliper. Torque all bolts to manufacturer specifications.
