My Tein SS has been squeaking in the back everytime i go over a bump. i do not know what is causing it to squeak. is there probably bushings? because one of my friends sprayed something on it and it stopped squeaking for a week, but after that, it started squeaking again.

will i need to rebuild the whole SS? or can something in there be fixed?
