Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, mechanic’s stethoscope, wheel chocks.
Park the vehicle on a level surface and turn off the engine. Engage the parking brake.

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is on the ground.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Check for Play: Grasp the hub and shake it to check for excessive play. If movement is observed, the bearing may need replacement.
Listen with Stethoscope: Place the stethoscope on the wheel bearing and spin the hub to listen for grinding noises.

4. Replace Wheel Bearing (if necessary)

Remove Brake Caliper: Unbolt the brake caliper and support it without stressing the brake line. Remove the brake rotor.
Remove Hub Assembly: Unbolt the hub from the steering knuckle. Remove any retaining clips if present.
Install New Bearing: Press the new bearing into the hub assembly using a bearing press or appropriate tools.
Reassemble: Reverse the disassembly steps to reassemble the hub, caliper, and wheel. Ensure all bolts are torqued to manufacturer specifications.

5. Final Checks

Reinstall the wheel and lug nuts, hand-tighten, and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications.
