Trust me, I'm not complaining or blaming the alignment shop. I simply asked what would cause this situation. This is not the first time I have redone the front end on a GN and I have never had a problem like this.
Yes, 0 degress Castor... like an idiot for the first time I did not ask for a copy of the printout. After sitting at the shop for 3 hours waiting for them to finish, I just wanted to get out of there. The shop manager told me it was 0 degrees castor and may pull on the crest of the road. I didn't realize how bad it would be. I may have installed something wrong, but I don't know what could have caused that kind of difference. The coil spring is in its pocket on the lower control arm. They removed well over a 1/4" of shims on both the front and back bolts.
I do have to return to center, and I guess that is my main issue with the way the car handles.
I will go back and see about getting the printout. It's a local Goodyear shop that has done me right with my other cars in the past.
The car has never be wrecked and I have owned it for over 17 years without this problem.
My big question is, how is castor adjusted on these cars? Do the shims control castor and camber?
