    Front wheel Shimmy

    Tank slapping, wrist breaking, wobbly wheel syndrome

    After crossing the bridge last nite i came across a piece of road that was a little rough (just by the pub on the bend) Which sent my steering into a fit, as i put in the first line

    At first i thought something had failed but after inspecting (as much as I could at the side of the road) I could not find any visable faults so ive put it down to the fact that Ive removed the damper and i never had this problem before i changed the EXTREME drag link angle to cure the bump steer

    What's your view's

    Cross steering set up using home made straight axle
    Ford Transit mk2 stub's (modiefied) to accept mk4 zephyr hubs
    Suzuki sj 410 steering box

    (i think i have some pics on here in my pics)

    I had this happen on my Capri Hirider once, scared the crap out of me ! Also seen Landrovers suffer from it when hitting a pothole.

    It's a combination of stuff creating a gyroscopic effect from one wheel that transmits through the entire steering gear and increses to a level that it can tear the steering from your hand.. It was probably always there and the damper took care of it.
    Primary cause is excessive caster, couple that with unbalanaced wheels, bit of slack in the kingpins and wheelbearings all contribute.

    I'd stick the damper back on and then find some potholes ( shouldn't be hard ) round your way that you can hit with one wheel . It's usually a specific speed related at moment of impact as well.

    Sorry Kev i should of stated, new king pins, new bearings, recently balanced wheels, 30psi pressure (might be a little high) Kpi and caster was built in to ford spec for the Transit when I built axle then when I changed the rear wheels and raised the rear of the car I then lowered the rear mounting points for the front springs to compensate (not 100% but around 5-7% rings a bell) also the speed was somewhere around 20mph

    But had to remove the damper as the now higher straighter drag link was occupying the same space so thought id try with out one

    Bump steer, I would say a min of around 90% gone
    Steering effort at stand still, LOADS
    Steering effort at a roll, Livable

    Above all happy

    Ok then people re fitted the damper a couple of weeks ago now

    And im glad to report (as this was the only mod) that it seems to of cured the problems of ripping the steering wheel out of my hands but unsure if it has actually stopped it

    Hopfully this will be the end but if it happens again Ill be back

    Had the same thing with the pick up. Mine did it all the time.
    I went completely through the front end, replaced tie rod ends, king pin thrust bearings etc, basically anything that seemed even slightly worn. Checked castor and toe in etc.
    This made a hell of a difference but it still did it very occasionally so a few weeks ago I fitted a steering damper and it is fantastic now! I have so much more confidence when driving it as I know it isn't gonna do it again.
    I know some will say that the damper is a 'band aid', and that there is still a fundamental fault there somewhere and that it is masking it, but I don't care. It has done the trick for me.

    Standard Volkswagon Beetle mate. £12 I think it was.
    So cal do a lovely chrome one for about £60 or black for £35 I think.
    They are exactly the same as the beetle ones.
    Mines black and is fairly un obtrusive where I have positioned it. Didn't really wanna show it off
    Agree with you and Kev though, it scared the **** outta me the first time it happened.

    Cross steer only?

    Out of interest - Iis it likely to happen to cross steering setups more than side steering arrangement?

    Mine was side steer on the hirider, Transit box. I would think crosssteer is more susceptible anyway as it the the set up most likely to require a panhard rod to provide lateral location

    You've resurfaced then Pete ?

    Hey Pete
    To be honest mate I don't know, there seems to be numerous resons as to why this happens (I have read alot!) from toe in and castor settings to worn king pin bushes and tyre pressures. It can be one thing or a number of seperate issues.
    I think the key is to make sure absolutely everything is set correctly on the front end and that there is no wear in any components.
    If that fails fit a damper! At least thats what I did.

    PS did the motor run alright? hope so.
