When Majors E30 was still in my possession I had allot of play on the steering wheel, up to the point where it was downright dangerous, I inspected and found that the rubber coupling was completely worn and broken, it was a very easy fix, I actually found a nice newish looking rubber coupling from the scrap yard and fitted it, the steering was perfect after that.
I would imagine that if the rubber cuppling is damaged enough that you could possibly hear a bit of a metal sound as the rubber coupling wouldnt be dubbing the sound? just a thought I guess.
