I just got an 02 wrx 5mt. A little back ground. Bought car two weeks ago thought center diff was going bad cause it was binding and when turn at slow speeds. Turns out it was a bad inner cv on the drives side. Changed it and fixed the problem. The other day driving home when I let off the gas a get a clicking noise like a playing car in the spokes of a bike. It seems to go away when I push clutch in or pop car in neutral or at least it quiets down enough I can't hear it over the road noise. The faster I'm going the fast the click. Checked all the other axles they seem solid no torn boots. Rear drive shaft has no play in the u joints. Clutch was replaced by previous owner by the dealer 20k miles ago. Any help on what to look for would great.
