Hey guys I got this really strange problem.
well what happened was i was driving, pulled over to the side to adjust the stiffness on my front coilovers. got back in and started to drive the car and i heard a rattling sorta sound.
-Only rattles when accelerating, no other way
-Only when clutch is engaged
-Lifted the car and ran it off the ground and the sound wasnt there anymore
-put the car back down and it started rattling again.

No sound when at idle, clutch disengaged, deaccelerating or when the wheels are in the air

 

Dw it was the rear left diff mount, all fixed
