Ok, I've had a rattle under my jeep for a few weeks now. When I checked it out, I discovered that the end of the torque arm stud had been snagged on something and broken off and the stud was loose. So, in with my best sherlock holmes attitude, I deduced that was the problem. But, I fixed that, and the rattle continues. It only does it when i hit a fairly big bump in the road, and it sounds as if it's coming from around the passenger side floorboard, but I can't find anything loose. I've kicked around on everything under there. The u-joints are all good, the tranny mounts are good, skid plates, etc. What else could it be? I vaguely remember a mention about something like this in another post, but I can't find it. Somebody help!
