I would think 5K is a good deal. Get a good alignment. The caster and camber are done with eccentric bolts on the upper a-arm. The setting are inter-related and take some fiddling and patience to adjust. Caster that is not even side to side may be responsible for the drift feeling even if all is tight.

You will also find a Mopar automatic much tighter than a GM. Do not sloppy shift from reverse to drive while coasting in reverse, like is often done in a GM.
