Solution

1. Preparation

Tools Needed: Jack, jack stands, wheel chocks, socket set, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for wear; replace if thickness is below 3 mm.
3. Check the rotors for scoring or warping; replace if necessary.
4. Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Check and Repair Drivetrain Components

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Inspect the drive axles for cracks or tears in the rubber boots; replace if damaged.
3. Examine the differential for any fluid leaks or metal shavings; repair or replace as necessary.
4. Lower the vehicle back to the ground and test drive.

4. Inspect and Replace Suspension Components

Sub-steps:
1. With the vehicle lifted, visually inspect struts and shocks for any signs of leakage or damage.
2. Check control arms and bushings for wear; replace if they show signs of wear.
3. Reassemble any components removed and lower the vehicle.
