Solution

1. Preparation

Gather necessary tools and parts for alignment and inspection.
Park the vehicle on a level surface and ensure it’s in “Park” or neutral with the parking brake engaged.

2. Check Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to match the manufacturer's specifications.

3. Inspect and Rotate Tires

Remove the front tires using a socket set.
Inspect for uneven wear patterns; if found, rotate the tires to promote even wear.
Reinstall tires and torque lug nuts to the manufacturer’s specifications (usually around 90-120 ft-lbs).

4. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings according to Porsche specifications (consult service manual for exact values).
Record the before and after alignment readings.

5. Inspect Suspension Components

Visually check control arms, bushings, and strut assemblies for wear or damage.
Replace any damaged components as needed.

6. Test Drive and Final Inspection

Conduct a test drive to verify that the vehicle no longer pulls to the right.
Recheck tire pressures and alignment after the test drive.
