Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Tires

Sub-steps:
- Check tire pressure using a tire gauge; inflate to manufacturer specifications if needed.
- Inspect tires for uneven wear; replace if necessary.
- If tires are balanced, consider rotating them to ensure even wear.
Tools Required: Tire pressure gauge, jack, jack stands, tire iron.

3. Wheel Balancing

Sub-steps:
- Remove the wheel using the tire iron.
- Take the wheel to a shop for professional balancing or use a wheel balancer if available.
- Reinstall the wheel and torque to the manufacturer's specifications (usually around 80-100 ft-lbs).
Tools Required: Torque wrench, jack, jack stands.

4. Inspect Suspension Components

Sub-steps:
- Visually inspect shocks, struts, and control arms for leaks and cracks.
- Replace any worn or damaged components.
- Ensure all bolt connections are tight and secure.
Tools Required: Socket set, torque wrench, inspection tools.

5. Check Driveshaft and CV Joints

Sub-steps:
- Inspect the driveshaft for any signs of bending, cracks, or wear.
- Check CV joints for any tearing of the boot or grease leakage.
- Replace any damaged components.
Tools Required: Jack, jack stands, socket set.
