The past two days I have had my evo out I noticed this happened twice. Whenever I come to a stop in traffic I put the car and neutral and wait until traffic is moving again. Well when I pushed the clutch in to put it in gear I heard a clunk that sounded like it came from the rear so looked in my rear view thinking someone had just rear ended me but nobody was there. I just brushed it off and it didn't happen anymore until today. The same thing happened. Any ideas?
