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.
No I haven't < but if I didn't change anything why should it need to be aligned? tire was not leaning with the 9" drums so why would it lean now? also why just the left wheel? ( I changed the lower ball joint , but same problem! ) also why is there no lean when backing up ? now if the lower control bushing is bad could this be my problem ?
can anyone tell me why changing over to disc ft brk will change the align and cause the left wheel to lean inwards? remmber I have the stock upper control arms with small ball joint bought inserts from diff doc that allows the small ball joint to be used , it goes over the ball joint shaft andfits the bigger hole for the spindal its a (shim ) and it works cause the right was leaning too !!! I didn't realise the ball joint where differant at the time . so need help asap any other indes???
