I have a 4x2 chevy silverado with a 3" lift, 33 x 12.5 tires. I replaced the ball joints 2 months ago because they were cracked. Then, my tires started going bald on the inside, rapidly. I took it to get aligned, and they told me it could not be aligned because the ball joints were broken again and I needed ball joint spacers to give it that extra 1/2 inch lift because the control arms were sitting on the frame. I took it for a second and third opinion and got the same answer. Basically, the guy that lifted the truck (I bought it with the lift already) left the factory control arms in there and they've been sitting on the frame putting pressure on the ball joints. To ease the pressure from the ball joints, spacers were used. Well, because of the spacers at least it could be aligned a little and therefore my tires aren't going bald on the inside.
I need to change the control arms (a-arms) to the after market kind to solve the problem. Can you help!
