    I have a skyjacker 4" lift, skyjacker hydro shocks, add-a-leaf w/3.5"blocks in rear, ORD steering brace, new single rancho stabalizer, new 33's, new bearings, new everything suspension, 4" raised steering arm,and all new poly bushings.
    So I still have steering bump pretty good and on bumps going down the road it twists as it settles on compression, a left right, right left motion. WHY??? I've done everything I can think of. The only thing left is new springs in the back. So I could really use some input about now guys, and gals. Thanks, Matt.

    Displacement, cubes, and did you say you drive a riceburner???

    Sounds like you've done everything you can...............the solution from what I hear is crossover steering. The stock short pitman arm is our problem on these stock-steer trucks...........any small input to the wheels is transferred immediatetly through the pitman to the steering wheel. I have much the same experience with my Blazer, when we did the one ton conversion, with all new EVERYTHING from the frame down, it still has a small amount of bump steer. I too added new rear springs, so that probably won't make an impact for you either.

    I'm sure other's will chime in.

    What have you done with the swaybar? I have heard the ORD diconnect/correction kit is the way to go. Also I would really recomend ditching the single stabilizer setup for a dual unit. I would try those two items before you go through the bit expense of crossover steering. I'll also assume the frt end and gear box are both tight.
