Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Tools Required: Jack, jack stands, tire pressure gauge, torque wrench, alignment machine.

2. Tire Inspection and Replacement

Remove the wheel from the affected axle using a jack and jack stands.
Inspect the tire for uneven wear or damage.
- If damaged, replace the tire with a new one that matches the specifications.
- Ensure the new tire is properly balanced before installation.
Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically around 100 lb-ft for Cayenne).

3. Suspension Component Replacement

If any suspension components are worn or damaged, remove them using appropriate tools.
- For example, if control arms need to be replaced:
  1. Remove bolts connecting the control arm to the chassis and wheel assembly.
  2. Install the new control arm and torque the bolts to specifications.
Recheck all related suspension components and replace as necessary.

4. Wheel Alignment

After replacing any tires or suspension components, perform a wheel alignment.
1. Use an alignment machine to adjust camber, caster, and toe settings to manufacturer specifications.
2. Test drive the vehicle to ensure proper handling.
