Vague Steering

[PCC]

Not an easy subject to get a simply answer............

I would like to find out what's causing my steering to act in a "vague" manner (bit like my mind).

When driving on an "uneven" surface (most of QLD roads) I find that the steering has a tendency to wander (feels light) and can quite easily pull to the left (if you dont have two hands on the steering wheel).

Lifted the rear suspension, but does not seem to improve things.

Running with jag front and back (single coilovers on the back).

I do find that the car does handle very well on a smooth surface and sticks like glue. It only accurs on undulating surfaces or at high speed (dangerous).

I'm wondering if its something to do with the flexibility of the chassis, but thats only guessing.

I think I may have to get the suspension setup professionally and check the alignments. However not keen to throw money into an area that I have'nt got the answer first.

Thanks guys
