The Corsa has still got an apparent issue with the steering.
We've so far had the track rod ends changed, full 4 wheel alignment, and a full re-balance done.
The car judders through the steering wheel between 60 and 70mph, and if the car is stationary, if you wiggle the wheel, there is a lack of resistance for about 25[sup]O[/sup] either way on the wheel.
I'm beginning to think it could be the steering rack which is on it's way out. Anyone else have any thoughts?
