I have a '95 960 sedan, and at present has 123,000 miles on it. For years this car has chewed up tires on the outside edges. I have had it back to the dealer and to Goodyear and Firestone with no success, other than saying that it was in spec.
Frustrated, I took an dres a perpendicular line to the ground and made a chalk mark on the ground, using the center of the tred as my guide. I backed up the car and measured with a wooden carpenters rule.
I found that after the dealer did the alignment the toe was 1 1/2" out.
It was nearly as bad at the other places I took the car.
I then adjusted the toe evenly on each side jacking up the targeted side and adjusting it 1/8 of an inch each side. Then measuring again.
I think that the sagging front springs caused the changes, but I would think that someone would know how to use their alignment rack. I gues I was wrong.
The car is much better.I have it nearly at 1/16" toe in. After moving forward.
I was taught years ago that if you jacked up the car, you took the force off the bushings and your alignment readings will be wrong. They are.
I thought someone might like the idea. It is not too hard to do.
