Vibration / Grinding Through Steering Wheel

[*Kosta*]

On my MY99 UK Turbo when cornering hard left, I am getting an awful grinding/vibration through the steering wheel.

I've had the OSF wheel bearing changed, but this has made no difference.

Anyone experienced this before? I'm going to the Nurburgring in 4 weeks so need it sorting pretty sharpish.

Help!

Thanks
