Steering Probs in SPOA FJ40

[DIRTY ROCK STAR]

Can anyone give me tips or a reason why?

when driving my FJ40 it seems to wobble at about 40-50kph but only sometimes and mostly after hitting a bump.
the steering wheel shakes badly. over or under this speed its not noticeable.
however it does wander a bit.
the diffs have been rotated.
is this a geometry problem or more something dead on it??

help will be much appreciated!

have the rims been balanced?
castor angles?
how have you mounted the drag links? hi steer, crossover steer?

When the diffs were rotated, were the knuckles cut and rotated aswell to maintain correct castor ?

And as 383FJ45 said, what steering setup are you running ?

you guys have been rather helpful.
but with the steering i honestly have no clue!
it has 75 series arms i think.
and i will check the knuckles as they have just been replaced.
i will sus that out.
had some issues wit ha dead diff so alot of shit got replaced and i now have fine spline diff and axle where before i had the older style apparently.
its all fucken dutch to me. i just like driving it, but would like to learn more!

sounds like castor angle problem to me. get a shop to stick it on an aligner, it might be correctable cheaply with wedges, if that won't screw your driveline angles too badly.

You need this done to keep the correct castor angles or it wont feel to good and may cause the probs !!!
