Solution

1. Tire Balance

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Mount the wheels on a tire balancer.
3. Add weights as necessary to correct any imbalance.
4. Reinstall the wheels on the vehicle and torque them to the manufacturer's specifications (typically 100-120 ft-lbs).

2. Tire Inspection and Replacement

Sub-steps:
1. Visually inspect each tire for uneven wear, bulges, or cuts.
2. Measure tread depth; if below 2/32", replace the tires.
3. If any tires are damaged, replace them with OEM or high-quality tires suitable for the Cayenne.
4. Properly dispose of old tires according to local regulations.

3. Wheel Alignment

Sub-steps:
1. Drive the vehicle onto an alignment rack.
2. Adjust the alignment settings to match the manufacturer’s specifications.
3. Ensure caster, camber, and toe angles are within acceptable ranges.
4. Test drive the vehicle to confirm that vibrations are resolved.

4. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Inspect control arms, struts, and bushings for damage or excessive play.
3. Replace any worn or damaged components with OEM parts.
4. Reassemble the suspension and lower the vehicle.
