Try loosening and re-torquing the nuts on the bulkhead to strut top reinforcement bars....

Hi,
I have had a simular problem which sounds like a bolt or metal object sliding when going around corners.
Had a look when head unit was out, had the steering column covers off and ashtray out but cannot find it.
Very frustrating but living with it as short of removing dash have given up.

I know exactly what that is. If you have been to France recently, a people smuggler has likely put an immigrant in there and he is trying to get attention before he starves.

Seriously? OK, will give that a go then.
Yeah, its not a rattle is it, more of a "knock" sort of noise especially when one front wheel goes over a bump before the other one and twists the front a fraction.
Did you use a torque wrench or just tighten them "feeling" the tightness?

You should be using torque plus angle, I've posted the values before but don't have them to hand.

If you have the rolling bolt sound its your torsion bar.
Easy fix and very strange that,thats what causes the rolling bolt sound.
