Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Engage the parking brake and use wheel chocks.

2. Tire Balance Adjustment

Remove the wheel covers if applicable.
Use a wheel balancer to check each tire and identify unbalanced areas.
Add weights as necessary to balance the tires.
Reinstall wheel covers (if removed) and lower the vehicle.

3. Tire Inspection and Replacement

Inspect each tire for uneven wear, bulges, or damage.
If any tire is damaged or excessively worn, replace it with a new tire of the same size and type.
Ensure all tires are inflated to the manufacturer's recommended pressure.

4. Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust camber, caster, and toe angles to meet manufacturer specifications.
Test drive the vehicle to confirm that it tracks straight.

5. Suspension Component Inspection

Visually inspect shocks, struts, and control arms for signs of wear or leaks.
If any components are worn, replace them according to the manufacturer's specifications.
Reassemble and torque all fasteners to appropriate values.

6. CV Joint and Driveshaft Inspection

Inspect CV joints for torn boots or excessive play.
If damaged, replace the CV joint or entire axle assembly as necessary.
Check driveshaft for bent sections or worn U-joints and replace if needed.
