my 2001 mille, 550 miles on it. I checked the rear cush drive nuts....1 was tight, 3 I could spin with my fingers. I tried to tighten the 3 that i could spin with my fingers and they just spin and spin!! there isn't anything to keep them from spinning...the stud that comes out of the rear wheel it is just spinning with the nut!!!! Like I said only 1 is tight, 3 keep spinning with my fingers, and the 4th, it spins with about 15ftlbs on it, and it keeps spinning and spinning.....What is the tightening procedure and how much ftlbs....I don't see how to keep the studs from spinning in the wheel??? Or do I have to take the wheel off and then will the whole cush drive come out, that way I can get to the back of the studs/bolts whatever they are. If someone could look up in there service manual and tell me. I would also definately suggest you go out real quick with 17mm wrench and see if yours are loose. Let me know what turns out...
