So when you're roadster goes in for it's scheduled maintenance, I'm certain they check the rear toe links and retorque them, as they loosen up quite a bit (on the frame end) and cause play in the rear toe. What else in the rear end tends to loosen up from normal use? I'm asking because I have a very noticable "clunk" in the rear, when I hit a bump. I checked the upper and lower control arms, sway bar mounts and links, upper and lower shock bolts, carrier bolts, etc. What else could it be? Motor mounts? Battery mounts? Anyone watch as they go through their servicing? Any common looseness other than the rear toe links? I haven't pulled the back diffuser and pan yet, but I'm going to have to, to find it. (First I have to make up some gradual ramps out of 2x12's to back the car up onto.) Any thoughts from those in the know? Thanks guys!
