Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Brake Inspection and Replacement

Brake Pad Inspection:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness; replace if less than 3mm.
Brake Rotor Replacement:
- If the rotors are worn or damaged, remove the caliper using a socket set.
- Unbolt the rotor from the hub and replace it with a new one.
- Torque caliper bolts to manufacturer specifications (typically around 25 ft-lbs).

3. Drivetrain Component Check

CV Joint Inspection:
- Inspect CV boots for tears or grease leaks. Replace if necessary.
- If CV joints are worn, remove the axle nut and disconnect from the hub; replace the axle.
Wheel Bearing Replacement:
- If wheel bearings are faulty, remove the wheel and brake assembly.
- Remove the hub assembly using a bearing puller and replace with a new bearing.
- Reassemble and torque hub bolts according to specifications.
