Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before proceeding.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Wheel Bearing

Locate the wheel bearing assembly.
Check for any signs of damage, rust, or excessive grease leakage.
Spin the hub by hand to feel for smoothness or any roughness.

4. Replace Wheel Bearing (if faulty)

Remove the brake caliper and rotor to gain access to the hub assembly.
- Sub-steps: Use a socket set to remove caliper bolts, support the caliper with a bungee cord, and remove the rotor.
Disconnect the wheel hub assembly from the suspension components.
Use a bearing puller to extract the old wheel bearing from the hub.
Install the new wheel bearing, ensuring proper alignment and fit.
Reassemble the hub assembly, ensuring all components are torqued to the manufacturer's specifications.

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts before lowering the vehicle.
Once the vehicle is back on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
