Solution

1. Preparation

Gather tools and materials:
- Tire pressure gauge
- Torque wrench
- Floor jack and jack stands
- Wheel chocks
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Tire Inspection and Pressure Check

Remove valve caps and check tire pressures using a tire pressure gauge; inflate or deflate tires to manufacturer specifications.
Visually inspect tires for any bulges, uneven wear, or foreign objects embedded in the tread.

3. Wheel Balancing

If tire inspection shows no significant issues, proceed to balance the wheels.
Remove the wheel and tire assembly using a socket set.
Mount the tire on a wheel balancer and follow the machine’s instructions to achieve proper balance; add weights as needed.
Reinstall the wheel and torque to specifications (typically 100-120 lb-ft for Cayenne).

4. Suspension and Driveline Inspection

Raise the vehicle using a floor jack and secure it with jack stands.
Inspect suspension components visually for any signs of wear, such as cracked bushings or bent control arms.
Check for play in the wheel bearings by grabbing the wheel at the 12 and 6 o'clock positions and wiggling; any movement indicates a need for replacement.
Inspect the driveshaft and joints for any play or signs of wear.

5. Alignment Adjustment (if necessary)

If the alignment is out, adjust using an alignment rack or take it to a professional.
Confirm alignment settings match manufacturer specifications.
