Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and securely lifted.
Tools Required: Jack stands, lug wrench, socket set, torque wrench, mechanic’s stethoscope, and wheel bearing puller.

2. Remove Wheel

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

3. Inspect and Remove the Wheel Bearing

Inspect: Check for any dirt or debris around the wheel bearing.
Remove Brake Caliper: Unbolt the brake caliper and hang it securely without stressing the brake line.
Remove Brake Rotor: Slide off the brake rotor to access the wheel bearing.
Remove Wheel Hub: Unbolt the wheel hub assembly, usually requiring a socket set, and gently pull it away from the spindle.
Extract Wheel Bearing: Use a wheel bearing puller to remove the old bearing from the hub.

4. Install New Wheel Bearing

Clean the hub area thoroughly before installation.
Press the new wheel bearing into the hub using the bearing press or appropriate tool.
Reassemble the hub assembly onto the spindle and torque the bolts to the manufacturer’s specifications.
Reattach the brake rotor and caliper, ensuring all components are securely fastened.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value in a star pattern.
