Solution

1. Preparation

Tools required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery for safety.

2. Brake Inspection and Replacement

Remove the wheel using the lug wrench.
Inspect brake pads and rotors:
- If pads are worn down to the indicator or rotors are scored, replace them.
- Clean the rotor surface with brake cleaner.
Install new brake pads and reassemble the wheel.
Torque the lug nuts to the manufacturer's specifications.

3. Wheel Bearing Replacement (if necessary)

Remove the wheel (as described in Step 2).
Remove the brake caliper and rotor to access the wheel bearing.
Use a socket set to remove the bearing assembly from the hub.
Press in the new wheel bearing using a bearing press tool.
Reassemble the rotor and caliper, then reattach the wheel.

4. Drivetrain Inspection and Repair (if necessary)

Lift the vehicle and inspect CV joints and axles for wear or damage.
If a CV joint is damaged, replace it by removing the axle from the differential and the wheel hub.
Install the new CV joint and reassemble the axle.
