Hi all I've got a MY00 uk turbo and have developed a judder only above 50mph when on the power turning to the right even slightly but goes when I let off the throttle but when in a straight line it's not there any ideas ? I've had the bearings checked could it be steering based or drivetrain based ? I have thought it could be the cv joints but there not making any noise or worse case front diff?
