    GD Jag front toe adjustment?

    Hi all,

    I have a question on how to get the front toe set up correctly on a Jag based Gd chassis.

    I can't get close to the 5 mins total toe in. This equates to 0.0833° total or 0.0415° per side I'm in the region of 0.3° and 0.5°. (both measured to the rear thrust line)

    There does seem to be any finer adjustment. A full turn on the track rod end give 0.83°.

    Any suggestions would be very greatfully recieved.
    Thanks

    Greg,

    From the wording of your post it looks like you're saying that the only adjustment you have is to screw the track rod ends in or out one complete turn. The track rods should turn inside the steering rack, so the way to adjust the toe-in is to slacken the track rod end locknut, then put a pair of mole grips on the track rod and turn it in or out a fraction of a turn to get the desired length. From your figure of 0.83 degrees per turn of the track rod end, 1/10th of a turn of the track rod itself (36 degrees) would equate to 5 minutes of toe-in.

    Apologies if I've misinterpreted your post!

    The toe is adjusted by turning the tie rods. There’s usually a square section under the rubber gaiter for that purpose.

    Thanks all I've just had the penny drop moment in the garage. There are no flats on the rod it's self to some delicate application of molecular grips is being used will have it sorted in a mo.

    Thanks again

    Be sure to adjust both sides equally or you’ll have a wonky steering wheel.

    So that's finally sorted.

    Both sides set correctly lined up against the rear thrust line. Hopefully no wonky steering.

    Now for the bump steer . . .

    You know you'll have to (probably) re do the tracking after setting the bump? Out of interest how are going to measure the bump steer?

    Yeah sorry my phone is making me sound somewhat more intelligent than I am. Molecular is not part of my every day vocabulary.

    Yeah I'm ready to re do it now it's not to difficult really.

    As for the bump steer methods I'm still trying to figure out the best method with the tools and kit I've got available.

    Hence any suggestions are welcome.
