Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, wheel chocks, mechanic's stethoscope.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect battery if working on electronic components.

2. Remove Wheel

Loosen the lug nuts using a lug wrench while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Wheel Bearing

Inspect the brake caliper and rotor for any obstructions.
Remove the caliper by unbolting it from its bracket (use appropriate torque values during reinstallation).
Remove the brake rotor to access the wheel bearing.
Remove the dust cap if present, then unbolt the wheel bearing assembly (use a socket set).
Carefully pull out the wheel bearing; if stuck, use a bearing puller.

4. Install New Wheel Bearing

Clean the hub assembly and inspect for any damage.
Install new wheel bearing into the hub, ensuring it is seated properly.
Reattach the bearing assembly using the appropriate torque specifications.
Reinstall the brake rotor and caliper, ensuring all bolts are torqued to specs.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer specifications.
Reconnect the battery if disconnected.
