When I shift into first gear and go below about 5-7MPH I hear a metal on metal grinding noise. It isn't constant, I want too say it almost goes with the rotation of the tires but it could also be something else rotating. Anyway I was wondering if you guys had any ideas as too what it could be, possibly a CV joint, axle or caliper? My driveshaft snapped in half and I haven't gotten it up onto a lift yet but I don't see how that could cause this sound but of course I could be wrong. Thanks for whatever help I get!

 

Turning doesn't affect it btw

 

If it's metal-on-metal grinding, there's sure to be marks left on a reciprocating part. While it may be unrelated, the "snapped in half" driveshaft would be the first place I'd look. What caused THAT in the first place?

 

maybe you have a caliper hung up and dragging on the rotor......

 

 

The sound was before, I haven't driven it since obviously hahaha

 

Gee... I wonder if the two issues might be related?

 

how did you break the drift shaft?

 

OP put the accident in a separate thread:

Hearing that he hopped a curb and damaged the bottom of the car means there could be damage to the front suspension causing this metal-to-metal sound. Since this Z is off the road, OP needs to inspect everything when the car is up on a lift or jackstands.
