Under the dash or the bottom front left under the car. Almost anything and everything. Could be a small rock or penny on the floor.
Give us more info. RPM, is car moving, any work done recently?
Some replied Yeah.
No work done in 3 years. Not a loose coin on on floor been there done that.
Does it in nutural or in gear just coasting or driving down the street and hitting any size bump. I have not put the car up in the air yet. It's more of metal on metal sound. It does sound more like it is under the dash though. Thanks for the input...Mark B.
