Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Measure the rotor thickness with a micrometer; replace if below specifications or if warped.
4. Install new brake pads and rotors, ensuring proper alignment and torque to manufacturer specifications.

3. Align the Wheels

Wheel Alignment:
1. Place the vehicle on an alignment rack.
2. Adjust camber, caster, and toe settings to factory specifications.
3. Test drive to ensure stability after alignment.

4. Inspect Suspension Components

Suspension Check:
1. Visually inspect tie rods, ball joints, and control arms for any signs of wear or damage.
2. Replace any worn components using a wrench set and torque to manufacturer specifications.

5. Balance Tires

Tire Balancing:
1. Remove the tires from the vehicle.
2. Use a tire balancing machine to check for imbalances.
3. Add wheel weights as needed and re-install the tires.
