I have been running the AC upper control arms for a long time now and my truck eats up ball joints like its cool. I also have had other front-end problems that I think may be related to problems inherent in those UCA's. So, in an attempt to alleviate these issues, I picked up some Rough Country UCA's to give me a better angle on the ball joint and hopefully end those issues once and for all. Everything is great with the new arms (especially the ball joint angle), however, they cannot get one side in alignment. It's close, but both the left caster and camber are slightly out of spec, and from what Schwab tells me, there is no more room to change things on that side. I'd not worry about it except that my truck now pulls to the left as a result and I'm sure it's going to kill my tires over time. I never had any alignment issues with the AC arms, so I'm thinking I may have screwed something up when I replaced 'em. My question is whether the bar that mounts the UCA to the frame could be incorrectly installed. I noticed that some writing on it is upside down, so I'm thinking maybe I put it in backwards. Do they have a specific direction that they need to be in order to line everything up? And if they do, is there a way to tell which way is correct?
