Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engages the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
- Inspect all tires for tread depth and visible damage (bulges, cuts).
- If necessary, replace any damaged tires with new ones (ensure to match OEM specifications).
- Re-inflate all tires to the recommended pressure as per the manufacturer's specs.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the hub using a socket set.
- Take the wheel to a tire shop for professional balancing or use a wheel balancer if available.
- Reinstall the balanced wheel and torque the lug nuts to the manufacturer’s specifications (typically 80-90 ft-lbs).

4. Suspension Component Inspection

Sub-steps:
- Visually inspect shocks and struts for fluid leaks or physical damage.
- Check bushings for cracks or excessive wear.
- If any components are damaged, replace them with OEM or equivalent parts.

5. Driveshaft and CV Joint Inspection

Sub-steps:
- Raise the vehicle on jack stands and inspect the driveshaft for any signs of damage.
- Check CV joints for any play or tearing of the rubber boot.
- Replace damaged driveshaft or CV joint as needed, ensuring proper installation.
