help! squeaking from axle/transmission

[boosted k20]

whats up!

this is the problem, when i drive slow i can hear like a squeaking noise coming from my passenger side. I decided to check it out so i removed my passenger side tire and spun the axle by hand. i noticed the noise is coming from the axle where it meets the transmission.

i think i might have messed something up with the car, cuz i occassionally pull out some burnouts and stand stills, and i think thats what messed up my car.
also i lowered my car with neuspeed race springs (2" drop) and i live in New York, where theres a pot hole like every other block. the car has went through a few pot holes and maybe that has contributed to my car squeaking like it is now.

any solutions to fix my problem??
