Rear clunking noise, only under acceleration
 

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!

Does it only clunk when you let on and off the accelerator?

could be your subframe bushings

you got a 2 way lsd?? i fixed my problem. one piece drive shaft and new subframe bushing and NEW GEAR FLUID

I almost have the same problem on my s13 but instead of clunking noise
It makes annoying creeking noise at the left rear.

****edit*** double post****

only when i press the accelerator. from barely pressing it to fully pressing it.

I put some SPL collars on there, but the actual bushings may be shot.

Well it had an open. Put a vlsd in and then it started making that noise. Thought it could have possibly been a faulty pumpkin, so I put the open back in. Still makes the noise. Maybe the extra length of the vlsd being ABS on my non-ABS car made the driveshaft and something along side it get out of whack.

yeah man, its very aggravating to say the least.

make sure the bolts from the axle to the diff arent loose! happened to me and i heard a terrible clunking

Have checked those also :(

check ur collars, check your axles for any play, check subframe nuts if their tight enough, basically re-tighten (or maybe too tight) all nuts and bolts that you took out initially when swapping aftermarket parts. lastly, check the 4 bolts that holds the hub.

??PLEASE someone let me know if this was figured out I have the exact same problem and they thought it was the drive shaft but 1 single piece drive shaft later it?s still happening!
