Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear, bulges, or cuts.
- Use a tread depth gauge to measure tread wear.
Replace Tires if Necessary:
- If tires are worn beyond safe limits, replace them.
- Remove the wheel using a socket set and jack stands for safety.

3. Wheel Balancing

Balance Wheels:
- Mount wheels on a balancing machine to check for imbalance.
- Add weights as needed to balance the wheels.
- Reinstall balanced wheels onto the vehicle, ensuring proper torque specifications (typically 80-100 ft-lbs for most vehicles).

4. Suspension and Driveline Inspection

Inspect Suspension:
- Check control arms, bushings, and struts for wear or damage.
- Replace any faulty components.
Check Driveshaft:
- Inspect for alignment and any signs of wear; replace if damaged.

5. Final Inspection

Re-check all components to ensure everything is properly secured and torqued.
Lower the vehicle and perform a test drive to assess the repairs.
