    Gasser front suspension and steering........

    Would like some pix and details of gasser style suspension and steering combos, or someone in the know to explain the best set up?

    Will try and explain how mine reacts, on acceleration you have steer to the right, on de-acceleration you have to steer to opposite way, even just driving normal hit a bump and the steering wheel will wobble, not vibrate just pulls your arms left to right if that makes sense?

    Huh? Why would anyone tolerate such obviously incorrect handling? I've had a gasser (built it) pop and it was arrow straight at 120 hands off. It went where it was pointed and onlt bit if it lost traction (regularly)

    Tony, some photos of the front end setup would be very informative.
    Layabout.

    I had a similar prob with a dropped tube axle in a Pop. If you hit a pothole the steering shake would pull the wheel out of your hands. Turned out to be castor angle which was set at about 7 degrees when we reduced it to about 3.5 - 4 it was 99% better.
    The other prob sounds like engine torque, does it have a panhard rod on the front?

    It sounds like alignment.

    I have no experience with straight axles but for steering to work correctly (ie using the Ackerman Principle the points where the lines cross should be just in front of where the yoke is on the front of the diff.

    If the steering tie rod still drops at an angle like it does in the photo I sent, then it is simply bump steer. I don't know what the spindles are (early Ford?), but if you are able to mount a steering arm at the top, i.e. above the springs if there is room, the tie rod would be nearer horizontal, which is where you want to be. Lowering the steering box could also help. As mr1958... says, I think this was what Vince was fighting with.

    Tony the problem is the difference in height between the box and the steering arm

    The only way around it is to fit a rack to the axle and a sliding joint on the colume (boring but safe)
