Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, wheel chocks.
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before working on it.

2. Remove Wheel and Brake Components

Loosen the lug nuts while the wheel is still on the ground, then lift the vehicle and remove the wheel.
Remove the brake caliper and bracket (if needed) by unbolting it and hanging it with a wire to avoid straining the brake line.
Remove the brake rotor to access the wheel bearing.

3. Replace the Wheel Bearing

Remove the Hub Assembly: Unbolt the hub assembly from the steering knuckle. Typically, this involves removing several bolts and possibly a nut on the axle shaft.
Extract the Old Bearing: Use a bearing puller to extract the old bearing from the hub assembly.
Install New Bearing: Press the new bearing into the hub assembly using a suitable tool to avoid damaging the bearing.
Reinstall the Hub: Bolt the hub assembly back onto the steering knuckle and torque the bolts to manufacturer specifications (check service manual for exact torque values).

4. Reassemble Components

Reinstall the brake rotor and caliper, ensuring all bolts are tightened to specifications.
Reattach the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle

Carefully lower the vehicle from the jack stands and torque the lug nuts to the manufacturer’s specifications.
