    Obviously the smaller the steering wheel the harder to steer hence with around a 14inch wheel I'd aim at 1:1.

    Shortening the pitman arm will also alter the arc the steering arms travels hopefully stopping some of the bumpsteer.

    The steering side rod position is almost in line with the rear 4 bars so should be good enough. What sort of tyre pressures are you running in the front ?
    OK, I'll give that a try and report back. Tyre pressures are 20 psi, did try higher but it made the wandering worse.

    Thank you again.

    Well I must say a big thank you to Al for picking up a second hand pitman arm and posting it to me. Cheers mate I owe you one.

    I modified it so I've got a 1:1 ratio between steering arm and pitman arm. It's not a lot better and still wanders about. I have to turn the wheel more now to get it move.

    I'm thinking that perhaps the Transit box wasn't a wise choice but I after trying for months to find something suitable it was about my only option.

    Pete

    Jagos used to use them in there B chassis's and I've driven loads of Transits which are fine. The other thing that Jagos did was to make up an idler arm that the steering box connected to and this then connected to the steering given an altered steering ratio again. The set up on my T seems good using a Transit box hang on a sec and I'll measure steering arm and pitman arm.

    Sorry, can't find them in the ****hole of a garage. I remember I set it to give 3.5 turns lock to lock in the T ,compared to about 5.5 lock to lock in the Transit . I haven't driven it but static it felt good, no lost movement and not too heavy with a 14 inch steering wheel. Pretty sure I had it 1:1 though .

    Is there lost motion when it's static , ie movement at the steering wheel before the arm shows any sign of moving as opposed to teh wheel moving ?

    Thanks Kev,

    No there isn't any lost motion, I think it's just too low a ratio combined with a bit of bump steer.

    Idler arm sounds interesting, I'd better do some googling to see if I can find some photos.

    I'm sure you've checked this already, but how much caster and toe in are you running?

    Might the difference be in the fact Jago used to use Mk1 boxes & Pete's using a Mk3? Sorry the modified Pitman hasn't made much difference mate.
    How'd the weekend go? Well, at the moment it looks like a dolphin that's been caught in a boats propeller.

    I've tried 1/8 to 3/16 toe in and 5 to 9 caster. Not a lot of difference.

    No worries, it was worth a try. Thanks again for you time and effort.

    Ah, please can you enlighten me as I've got no idea what the difference could be?
