Rear clunking noise, only under acceleration

[kyleshell]

Ok so I am about to pull every hair out in my head at this point. There is a clunking noise from the rear, towards to back right wheel of my S14. I have coils, RUCA's, toe rods, traction rods that are aftermarket back there. Stock rear brakes.
Ok so here's the problem. When I start off in 1st gear, nothing makes noise. In every gear after that, this clunking noise begins. It only happens when the car is under acceleration, when there is force/pressure being applied. I have gone through several phases of lowering and raising the car. Before I raised it up a little bit, the car was pretty low. And at that height it never made this funky noise. But when I raised it back up to where is sits now, that's when it started. I have checked every link, nothing is rubbing, etc...I don't know what else to frackin do. Someone pleeeeaaaase shed some light on this sitiation!
