I have a problem with my LCR,its on ap adjustable coilovers and there is a terribly strange knocking/rumbling/grinding noise coming from the O/S/F somewhere.Now i have replaced all four Ball joints,Polybushed the Cast Arms,Replaced both Wheel bearings Front discs and pads and the O/S driveshaft,But still the noises are there,I am a vehicle Technician and had it over the pit at work,and everything seems OK,no play in anything it doesnt make the noise when the front end is jacked up and driving in gear,its totally Doing my head in to the point of me not enjoying driving it. So if anybody could shed some light on the matter for me or had similar problems i would be very grateful
