    Honestly here, my friend, you're asking alot to try get a chassis diagnosed over the internet. Did you build the car? Or did you purchase it from someone else? What you have sounds a little scarey, the frame tiself may be straight, what about the shock location, did the previous owner(s), do something unusual. Is it a leaf sprung or coil sprung car? Is the ladder bar location correct, there has to be a reason you have a bias?

    Not trying to be a smart a-- here, you need to find someone in your area that has built a car or two and have them look at it. I know I've been away from this for a long time but a truism still exists, "oftentimes people sell cars for reasons other than just needing money". A friend of mine bought a "bent" Super Stock Chevy II in the mid-80's and proceeded to put a BBC in it, trust me, he only created more problems for himself. He didn't discover this until after the fact and only enhanced the problem with the higher HP motor.

    Good luck and I hope you can find a fix.

    yes the front mounting points are exactly the same measurement. i dont see the shock mounts being a problem shock are off the car. really it looks like the ladder bars are way off on adjustment. would that not make the rearend off?

    ok what if my car was setup for a really big guy? that would make it high on the driver side with nobody or some one lighter right? i would need to adjust the bars for me which should make it level with me in it. does that put me on the right path?

    suspension

    I'm a little nervous on this. Trust my judgement here, I'm no chassis expert like others on this board probably are.

    Given what you're telling me. If the bars are adjusted unevenly, if you take a tape and measure center to center of your wheels, front to rear or vice versa, your measurement ought to be squirrely. Your front to rear measurement should be fairly square, I'd say at worst within 1/32 - 1/16 of an inch at worst. You get the wheels out of wack, the car is gonna track real funny, as in dangerous. Heims adjusted too far out create another dangerous situation. I know this first hand, really sucks when a heim comes out. About wrecked my car at Terre Haute, Indiana over this once. Had the heims adjusted with too few threads in the bar, under hard accelleration, the heim pulled it's remaining threads out.

    With ladder bars, adjust the heims out, you move the rear in or out, to move the angle up or down, you move the bars up or down. This still doesn't address your side to side bias. Unless what you're saying is, one side of the bars are set up in a different hole than the opposite side?

    I'm only throwing this out because I'm preparing to put a 4 link under my old car that has been parked for 20 years. I've never done a suspension myself, I'm more than a little nervous. A friend that has built a couple is helping me, so, I'm having to put alot of faith in his judgement and abilities. I've seen badly set up cars do some equally dangerous things.

    I'm going back to my first post. Find someone with chassis knowledge and have them crawl under that car with you.

    I tried to adjust mine with weight simulated in the seat and set it level like that and the thing pulled like crazy to the right all the way down the track.
    So I set it level with it's own weight and it drives straight as can be.
    I am not sure why it is differant for me but it works...
    Sounds like to me you have too much pre-load in one side. Are your bars double adjustable?

    Do the ladder bars have an adjustable link on the lower rear portion of the bar? If so with the shocks off, if one side is hanging lower the preload may have been set differently than the other or something is binding up. It is typycal for the driver side to be lower than the passenger side, not the other way around. There are many scenarios which could cause this. But I would start by ensuring all the rod ends are adjusted out equal amounts. If it still is an issue, start looking at bracket mounts on the rear end housing, maybe they aren't in the same location on the housing.
