I have a MY97 Type Ra fitted with 4.444 diffs front and rear and LSD in rear. The car goes like a rocket in a straight line with no noises whatsoever, but when I turn a corner especially when going slowly I get a severe grinding / vibration which appears to come from the rear. LSD and centre diff have been checked, all appears ok. Any gurus out there able to cast a couple of suggestions greatly appreciated.
