Ok well abit of an update. Upon driving my car to Brisbane from Wagga Wagga NSW for my Christmas holidays i noticed that my steering issue is worse.
A mate and myself jacked her up and pulled the wheels off the fronts, to have abit of a look and see if we can see anything that looked out of place. First check we did was grabbing the brake rotor and gave it a good wiggle. I would have to say it had between 3 and 7mm of play .. indicating that the upper ball joint / something in that general area was completely rooted. As far as i know there is supposed to be ZERO play.
We also checked the otherside, there was a tiny bit of play there as well but no-where near as much. It all makes seems to make sense to me, the RH ball joint had the most play .. and my steering issue was when turning left. The RH side would load up under the weight of the car pushing outwards, and at a certain point the force would be great enough to allow the wheel / rotor / ball joint to "shift / play" mid-courner .. increasing the amount of camber on the outer wheel resulting in an increase of the already instructed turn.
I'm not sure if that is entirely correct (feel free to correct me) however i think it explains my cournering issue perfectly. I had to leave my car in Brisbane though due to the floods, so i won't be able to get the ball joint fixed for another 2 months or so to confirm my prognosis. But i thought i'd update this thread to let anyone else who has similar issue's know what / where to check
Thanks BWRGTR, as your suggestion was dead on.
I just diddn't think it would have been something so obvious.. my mechanic couldn't find it (isn't it the first thing to check, play in the rotor / wheel that is) .. so i think from now on i'll try and fault find my own problems!
Hope this helps.
