Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Tools Required: Jack stands, lug wrench, OBD-II scanner, torque wrench, wheel balancer.

2. Tire Inspection and Replacement (if necessary)

Inspect the tires for uneven wear or bulges.
- If damage is found, replace the affected tire(s).
- Ensure all tires are inflated to the manufacturer’s specifications.
Rebalance the tires if they are in good condition but out of balance.
- Use a wheel balancer to adjust weights accordingly.

3. Suspension Component Check

Raise the vehicle using a jack and secure it with jack stands.
Inspect control arms, struts, and bushings for cracks or excessive wear.
- Replace any worn components with OEM parts.
- Torque bolts to manufacturer specifications (typically around 80-100 ft-lbs for suspension components).

4. Drivetrain Inspection

Check CV joints and driveshaft for any visible damage or excessive play.
- If any component is worn, replace the affected part.
- Ensure all fasteners are tightened and secure (typically around 30-50 ft-lbs for CV joints).

5. Final Assembly and Test

Reinstall all components, ensuring everything is torqued to specification.
Lower the vehicle and perform a test drive to confirm repair success.
