I raised the front of my truck about 1 1/4 inches higher then stock. When I took it in for a wheel alignment the tech said that he ran out of adjustment for the caster on the right front wheel (rear adjuster cam). As a result he could not adjust the camber any further either. I spoke with him and he said that it was close enough to spec so as to not hurt anything. There is however still adjustment left on the right side for both caster and camber. What can be done so that the alignment can be fully corrected without lowering the truck? Could the lower sub frames that attach the lower control arms be misaligned from the factory?


Thanks for your answers

I bought some new cams off ebay for mine. They raise the truck higher than the factory ones. With these you could leave the heigth you have it now and still have adjustment room. I think they were advertised on ebay as a leveling kit. They were around $90.00. I actually raised mine higher in the front than it was in the back. I installed a 6" fabtech lift later on, the replacement cams are still in also. Before I got the cams I had run into the same problem you are having.

Using the leveling kit will not change anything in regards to being able to achieve GM's alignment specs. You will always end up with caster too low whenever the front end is cranked, regardless of the method used. Caster is the measurement of how far the upper ball joint is behind the lower ball joint. The more farther back the upper is, the more positive the caster is. The front end geometry changes as the control arms go through their cycle. Have them adjust the maximum caster they can achieve while still keeping camber close to zero. Caster will not wear tires, but camber and toe will. Low caster will result in wandering, but the one or two degrees that you cannot get will not be enough to feel.
