1. Remove the wheel covers or hubcaps if necessary.
2. Inspect tires for any visible signs of damage or uneven wear.
3. Check tire pressure and inflate to the manufacturer’s recommended levels.
4. Balance the tires if they are out of balance; use a tire balancer for accuracy.
5. Replace any damaged tires if necessary.

3. Suspension and Alignment Check

Sub-steps:
1. Visually inspect suspension components (control arms, bushings, struts).
2. Look for signs of excessive play or damage; replace any worn components.
3. Perform a wheel alignment using an alignment machine to ensure proper handling.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Lift the vehicle securely on jack stands.
2. Inspect the driveshaft for any visible damage or excessive play.
