    New 4" narrowed beam all in but I'm confused why the steering is a mile out as i didn't undo or adjust anything i simply cracked the ball joints i even but the tierods in the cab left & right so they went back on the same side.
    With the drivers side wheel pointing straight the passenger side is turning left.
    And full lock left is terrible.
    So where do i start?
    Drop the drag link and adjust the two tie rods?[​IMG][​IMG][​IMG][​IMG]

    Disconnect one tie rod end of one tie rod.
    Point both wheels forward the measure how short the tie rod is from making it to the knuckle. However short it is is spprox how much wider your new beam is compared to the previous.

    Did your arms bolt onto your shortened leaves ok?

    The old beam and the new beam are both 4" narrowed so the leaves went on just fine.

  6. Looks to me like one beam is/was narrower than the other. Can we have photos of both wheels on the same image, please?

    The angle of the rods is different because the ends of the arms on the hub assemblies are at a different height. As the bus drops they get flatter so the hypotenuse of the triangle (rod length) is the same, angle smaller, cos(angle) gets bigger.

    Now go and look up tracking with a tape measure, adjust both arms the same, or if only one adjusts, drag link adjust after adjusting arm...it can be done.

    It would also be correct if you jack up the beam so the wheels return to the same height.

    Yes it's a stronger aftermarket one
    Mate of mine works at a engineering firm so he chopped and rewelded it at work for me.

    Centered steering wheel then Adjusted tie rods so both wheels are straight.
    But on full lock drivers side is 2" to Arb & passenger is 1"
    I assume i have to adjust the drag link then re adjust the tie?[​IMG][​IMG]

  12. i'll be interested how you get on with that - narrowing it will make it even stiffer (more resistant to twisting action). I have a standard front bar narrowed to fit my beam (-8cm) and heavy duty on the rear - seems to work ok together.

    I did have it on the old narrowed beam
    I've never driven without one so I've nothing to compare it to realy.
    I also have the rear one.

  15. It will probably snap , welding a hardened and tempered spring will fail eventually

    With two adjustable rods you have to be more careful. Both should be the same length near as you can. Then centre the box and finally adjust the drag link. You should then have equal lock each way and be on the tight part of the box going straight.

    How much adjustment did it take to get the wheels parallel?

    Not that much really passenger side out about 2cm drivers side in about 1cm.
    Also the big nut on the drag link is it fixed to the rod or is a a lock nut and unscrews?
