1. Prepare the vehicle. Park the vehicle on a level surface and turn off the engine. Engage the parking brake.
2. Locate the alignment adjustment points. The alignment adjustment points on the Passat are located on the front and rear axles. On the front axle, they are located at the base of the strut housings. On the rear axle, they are located on the lower control arms.
3. Loosen the alignment adjustment bolts. Use a wrench to loosen the alignment adjustment bolts at the front and rear axles. You should loosen them enough so that the bolts can be easily turned by hand.
4. Adjust the alignment. Use an alignment rack to adjust the alignment of the vehicle. Follow the instructions on the alignment rack to make the necessary adjustments.
5. Tighten the alignment adjustment bolts. Once the alignment has been adjusted, tighten the alignment adjustment bolts. Make sure that the bolts are tightened securely.
6. Test drive the vehicle. Test drive the vehicle to make sure that the alignment is correct. The vehicle should drive straight and true without any pulling or wandering.
* If you are not confident in your ability to perform this task, it is best to take the vehicle to a qualified mechanic to have it done.
