Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, wheel chock, safety glasses, and gloves.
Safety Warnings: Ensure the vehicle is on a flat surface before lifting and use jack stands for safety.

2. Remove Wheel

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

3. Inspect Wheel Bearing

Visual Inspection: Check for any signs of damage or excessive grease leakage from the wheel bearing.
Remove Brake Caliper: Unbolt the brake caliper and secure it away from the rotor (do not let it hang by the brake line).
Remove Brake Rotor: If necessary, take off the rotor to access the wheel bearing.
Check Bearing Play: Using your hands, check for any play in the hub assembly.

4. Replace Wheel Bearing (if necessary)

Remove Hub Assembly: Unbolt the hub assembly from the steering knuckle.
Install New Bearing: Press or hammer the new wheel bearing into the hub assembly.
Reassemble: Reattach the hub assembly, brake rotor, and brake caliper. Ensure all bolts are torqued to the manufacturer's specifications (typically around 80-100 ft-lbs for the hub assembly).

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually 75-85 ft-lbs).
