The GU not driving straight...

Andrew , I never saw your original thread , but took a read now. I dont think a castor kit is your answer. If you take a stick and place it vertical against the wheel. Mover to and away from the guard. This is your camber movement . Only effected by the up and down movement of the vehicle . I think your steering wheel hasn't been set up correctly in your wheel alighment . A wheel needs to be set at 11 oclock in a wheel alighment to allow for the camber of the road. The reason you notice it more on a hwy , is because they have more camber than city streets.

Andrew I agree entirely with Eric - a cater kit will only address the problems inherent with raising or lowering a vehicle. You appear to have the same (or similiar) problem that I have with my GU. I recently took it to NQ Truck Alignment Centre in Cairns on my way back from Cape York and they advise me that this problem could be fixed by realigning the steering wheel. Didn't have it done at the time as it requires that the battery be disconnected for a while to disarm the airbag properly (so I was told) before the steering wheel can be removed. The guy that did the alignment said the problem would be fixed by realigning be just one notch on the spline.

G'day Andrew,
Have to disagree, sounds like you do need a castor kit to correct a small
problem which your big tyres may be exagerating.
Wheel alignments are fairly complex which are a lot more involved than the
standard $35 check which usually is just a toe-in adjustment.
Sounds like the vehicle tries to pull left which is more than just an off-centre steering wheel.

Cheers
