  • How long should I adjust my control arms?

    Okay just got my new lower front control arms for my jeep. Now the question is on a 4" lift how much longer should they be than the stock ones? (they're adjustable)

    There is a fine line you need to walk between proper caster and proper pinion angle. I think the factory service manual states that pinion angle takes precidence over caster. Inncorrect caster will cause death wobble, and incorrect pinion angle will cause vibes and wear out your u-joints. So you need to find a happy place between the two. I'm not realy sure how you measure caster. I just drove my TJ, if it wobbled then I came home and adjusted my control arms a little, and repeated the process. I'm sure there is an easier way, but nobody wants to tell me, I guess. Any competent alignment place and measure it and get it where it needs to be. Good Luck.

      Well I decided to go half an inch longer than the stock arms... seems to work cause I took it out for a test drive, hit every bump I could and no wobble. I'm keeping my fingers crossed on this one.
