tire lean

Did you have it aligned after you got through? If the tire leans in toward the car at the top as viewed from the front, that's called negative camber. The spec is probably somewhere around -.25 degrees to +.25 degrees. ......or at least that's where I would recommend it. If it's obvious to the nekkid eye, it's probably out of spec. As Scott says, the bushings would be a good place to look for trouble, but if you have not had it aligned since working on it, that's the first thing I'd check. If it has bad parts, your alignment man will tell you.
