G'day Chris,
Yep I can understand what your talking about. Because the 1600 has a
narrower track than the semis, the contact patch of your front tyres are on
slight camber due to the road surface. Sort of like a bush 4 wheel drive
track with two gutters with a hump between. Unfortunately the gradient the
road is to your tyres means that the road slopes up to the center line of
your car on both sides. OK so when you brake hard to stop at the lights, ie
weight transfer to the front wheels, then the car wants to dart from the
left to the right. If this also occurs during normal driving on these roads
reposition the car in the lane differently ie stick one wheel where the
semis wheel would be and the other on the hump.
Personally I don't think this is your cars problem but the roads.
Try some hard stops on some good flat road. If you still have this problem
then your steering or suspension joints (Radius rod bushes, if under
braking) may be worn.
If in doubt get one of those pedders $14 checkups done. You can probably
then buy the bits you need off them and fit them yourself then get a wheel
alignment (Now ~$40 at Bobs because of GST).
Regards
Trev

Hi Terry,
My car isn't lowered at all as far as I can tell, It sits quite high. My
tyres are 185/60/13s Yokohama A510. It does get pretty skaty in the wet, but
the tyres only have about 30% tread left so a fresh set will probably help
there. Braking is normally good. It's only if there are cracks or ridges
running parallel to the direction of travel that it wanders. Over normal
potholes and dish gutters, dips etc it doesn't wander or steer.
At all the sets of lights around here, the soft tar for about 100m before
the lights has large indentations from semis braking and poor maintenance.
There are double wheeltracks with the soft tar squeezed up a bit in a hump
in the middle. The dat is a little narrower than the hump and wanders from
side to side on the crest of the hump even when there are no bumps at a
steady cruise. So I don't think this particular problem is bump steer
related. (Does anyone else experience this too?) To me it feels like it has
too much toe out, I'm going to check it out on the weekend.
I will also look out for worn suspension bits too.
Thanks for the advice,
Chris Howard
