Re: front end problem?

I'm not sure of the exact specs, but you should have a small amount of toe in. 1/16 in or so.

Negative (-) castor angle means the centerline of the upper balljoint is in front of the centerline of the lower balljoint.
Positive (+) castor is just the opposite. Upper BJ behind the lower BJ. I think just about a vehicles use posative castor nowdays.

Old Chevelles had negative castor. It was setup that way to make the steering easier but it wasn't good for stability at all.
