Funny noise from the rear plz help!!

[SUPERHICAS180]

I had just installed new jic coilovers and rear jic camber on my s13
after the installation my car made funny noises somewhere from the rear end.
It sound like my drive shaft is lose and it vibrates.
the sound only comes on when i accerate going over 25mph other than that it doesnt make any noise if i let off the gas pedel
I had check the suspension and camber and there all tight and looks properly.
I can figure out what it is.
can it be the drive shaft?
or because of me jacking the car from the lsd??
anyone know if theres any kind of bushing on the lsd that i might've killed?

plz help!!
