Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Lift the Vehicle

Loosen the lug nuts on the wheel associated with the suspected bearing issue.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel by removing the lug nuts completely.

3. Inspect the Wheel Bearing

Visual Inspection:
- Check for any visible damage to the wheel bearing seal or the bearing itself.
- Look for signs of grease leaking from the bearing area.
Physical Inspection:
- Spin the hub by hand and listen for any unusual noises (grinding, roughness).
- Grasp the hub at the 12 and 6 o'clock positions and check for play; there should be minimal to no movement.

4. Replace the Wheel Bearing (if necessary)

Remove the Brake Caliper:
- Unbolt the brake caliper and secure it (do not let it hang by the brake line).
- Remove the brake rotor if necessary to access the wheel bearing.
Extract the Old Bearing:
- Use a bearing puller to remove the old wheel bearing from the hub assembly.
- Clean the hub area where the new bearing will be installed.
Install the New Bearing:
- Apply grease to the new bearing as recommended by the manufacturer.
- Use a bearing press or appropriate tools to install the new bearing evenly and securely.
Reassemble:
- Reinstall the rotor and caliper.
- Reattach the wheel and hand-tighten the lug nuts before lowering the vehicle.

5. Final Steps

Lower the vehicle to the ground.
Torque the lug nuts to the manufacturer’s specifications using a torque wrench.
