Ok i have the 4 banger 5 speed, and recently i have this vibration and wicked noise coming from under neith my jeep but only during certain times. If im in neutral and not moving i can rev the engine some and feel a vibration under my feet, and i hear a wierd noise kinda like a piece of metal rubbing/bouncing around. But in first gear at the start of take off it does it for a slight bit then goes away, in third gear while accelerating or decelerating it does it quite a bit. I thought it was exhaust rubbing but i checked it and its tight n solid. I did a service on the trans a few weeks ago what else could it be? Any suggestions??

Maybe a blown cat? When they start to break apart inside it sometimes sounds like marbles rattling. But not if you have full power. Posting a YouTube video of the sound would make it easier for others to figure out.
