When I got my impala it needed a new frame and they put a 9c1 frame on. I took it to my alingment guy and he said the front of the frame needed to be pulled out about a 1/4 inch so he couldn't get all the shims on, so he aligned the best he could and said it's fine but you ought to let them pull the frame out to get it proberly aligned. Well it rode pretty good and then I got some billstein shocks and hotchkiss springs on. Looked good, but I started to notice a popping noise on the front passenger. Couldn't remember if I had it before or not. I started to notice my front tires wearing to the inside. I take it to the guy to pull the frame so I can get aligned just right,give him the specs, and he says the frame is straight the springs are the problem. My tow is way off and my tires are sitting like / \, of course not that bad. He said it sits to low and I don't have much room. He also said the driver's side is almost fine and the passenger side is real bad.I don't drive it much except for nice days and my tires are almost bald on the inside and are like brand new on the outside. To fix the problem he has to put my stock fronts on. I want the hotchkiss springs on there, but supposedly thats the problem. Is something wrong? what's goin on? Alot of people have this setup with no problems. I am getting pissed. Any knowledge on the subject will help. please.
