The squeaking is probably the bushings since mine was doing that last year as for the drift theres was a drift but i didnt replace them until one broke. The new ones i out on squeak when it rains but i already got used to the sound.

 

Which sway bar bushing did you get? I like that there's a nipple for re-greasing.

 

probably moog, that is the favorite brand for suspension components

 

i got the energy suspension on the front and back. theyre good on the back but they didnt last on the front. the edges ripped a few weeks ago on the front ill be switching to the moogs up front.
