    ok I have been running a 4" lift for about a month and have had no steering issues using the stock steering arm. Well I finally got around to installing a raised steering arm and now I have a bump steer kind of pull about 30mph. WTF did I do wrong? I used a BIG hammer to pound the number that are stamped on the original arm (Which I read on a thread here) and it came off without a lot of hassle. Any ideas? Thanks

    a steering arm should not have any effect on your axle alignment. i would look to see if you damaged your balljoints while removing the old arm.

    how level to the ground is the drag link? if it is level, you should not experience a lot of bump steer. but if you installed shims between the axle and the springs that will not help your situation.

    As far as the drag link goes it is pretty level, a whole lot more level than it was before the new arm. Dumb question here, how do I tell if the ball joint is bad?

    Adam,

    I installed a 4" lift and used the stock steering arm for a while also. I then installed the one for a 4" lift (Part # GM440 in think) and it seemed to me to be doing as you discribed.

    I noticed a few things; first was that the new steering arm was longer. I also notice that I could no longer make as sharp left hand turns.

    I adjusted my draglink and all seems fine.

    Apparently I got use to the bump steer issue because I don't feel it anymore. It may have just been that we were use to the operation of the stock one. /forums/images/graemlins/dunno.gif

    You need to have the draglink parellel to the spring, not the ground.

    could you explain your reasoning, that doesnt make sense to me.

    All I can add, is that people who have had this problem, have corrected it by making the draglink parellel to the spring, and not the ground.

    You need to have the correct angle in the draglink (with respect to the spring) so that as the spring compresses (and the axle therefore moves rearward) it doesn't turn the tire.

    It seems that many raised steering arms are actually too tall for a regular 4" lift.
