1. Remove the wheel covers or hubcaps if present.
2. Inspect tires for uneven wear, bulges, or damage; replace if necessary.
3. Check wheel balance using a tire balancing machine; rebalance if needed.

3. Alignment Check

Sub-steps:
1. Measure the wheel alignment using an alignment tool.
2. Adjust toe, camber, and caster angles as per manufacturer specifications.
3. Test drive to confirm alignment correction.

4. Engine and Transmission Mount Inspection

Sub-steps:
1. Visually inspect all mounts for cracks or separation.
2. Replace any damaged mounts with OEM parts using a torque wrench to the specified torque.
3. Recheck for vibrations after installation.

5. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect driveshaft for bends or damage; replace if necessary.
2. Check CV joints for wear; replace if there is excessive play or torn boots.
3. Ensure all fasteners are torqued to specification.
