I have recently found that something in the rear axle area of my car is clunking rather loud whenever I downshift and let out the clutch fast. Previously I was able to downshift without there being any noise. I've looked underneath and nothing seems to be out of place, it has new poly ended boxed control arms and an adjustable panhard bar, so neither of those things seem to be a problem. The noise seems to be concentrated by the passenger side. It also makes no noise under full throttle upshifts so I don't think it has anything to do with the torque arm either. Any ideas?

Solved it... it was the torque arm mount - it was just broken on the bottom side, not the top.
