    I own a 2003 mustang gt and have been hearing a nasty grinding, metal on metal noise underneath my car. Been told it wasn't my u-joints, rear end is good, tranny has no metal shavings, just replaced the tranny mount, and I have no idea what it could be so i need your help!!!!

    I assume you have an upgraded suspension. But just in case have you inspected it. on my 2000, I had a noise like that and during the restoration process I lowered it. When the tech removed the front springs one was completely broken the other had cracks in it.

    Never hurts to inspect your u joints, but the last time I had a u joint go bad on an SN95 it made a clunk type noise, not a grinding noise.

    Do you have a aftermarket midpipe or damaged/bent exhaust or heatshields? I had a clamp improperly aligned on my x pipe and it rattled and ground against the subframe. Very well could be the suspension too, as previously noted.

    the grinding was happening way before i lowered it..... the sound is right underneath my seats as previously noted and is very large noise and annoying

    When I did springs on my old 96' GT I too had a broken spring on the front PS. Surprised me that it never made any noise or acted funny on the road at all.

    Seems like the SN95s are quirky. Mine made noise, squeaked spit ground you name it. Upgraded the suspension with my restoration project and now I just have the normal but annoying interior trim squeaks and rattles which I will attack in due time.

    Hell my 13 has a nosy driver door, hit the small bump in the road and the door chatters. Dealer Body shop has adjusted it 3 times. It quiets down then within a few hundred miles it get chatty again.

    OP, does the car have subframe connectors and/or seat brackets?
