Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, OBD-II scanner
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery for electrical safety.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to raise the front or rear of the vehicle as needed, then secure with jack stands.
Remove Wheel:
- Using a socket set, remove the lug nuts and take off the wheel to access suspension components.
Inspect Components:
- Check struts, shock absorbers, control arms, and bushings for wear or damage. Look for cracks, tears, or excessive play.
Replace Damaged Parts:
- If any components are damaged, replace them with OEM or high-quality aftermarket parts.
- Follow manufacturer specifications for torque values when re-installing components.

3. Inspect and Repair Drivetrain

Examine Axles and Differential:
- Inspect the axles for signs of damage or wear. Check for any loose bolts or connections.
Tighten or Replace:
- Tighten any loose bolts and replace any damaged axles or differential components as necessary.

4. Reassemble Vehicle

Reinstall Wheel:
- Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and then use a torque wrench to tighten to the manufacturer's specifications.
Reconnect Battery:
- Reconnect the battery and ensure all electrical connections are secure.
