On my old xj, my exhaust pipe was rattling against the transmission crossmember. You couldn't see it moving, but as soon as I fixed the problem it went away.

you have to replace your deck with a good quality aftermarket cd/mp3 player. add in some nice speakers with good wiring and top it off with a nice amp/subwoofers, and the rattle will be gone.....................or you'll start getting even more. LOL


look at your exhaust the entire lenght of it. look for clean or worn spots, look for very tight spots that might come in contact if the exhaust moves a hair. rattles really aren't hard to find if you work front to back and pay attention, and not just the quick "one knee on the ground and a quick peek under the jeep" inspection.

Check for this
mayby a bad vibration damper on the crankshaft. Outer ring where the belt is running has become loose from the rubber isolation on mine. The ring touched finally the timing chain cover.

Result: Sometimes a rattling noise in P and N of transmission

Check the doors? Things like window regulators are relatively heavy blocks hanging off the thin sheet metal and they amplify vibration, eventually causing the sheet metal to tear, producing a buzzing rattle at the right vibration frequency.
