Did you changed yours ? for sure you need an alignment. My suspension is squeaking on bumps , i think the anti-roll bar or the wishbones.

 

No, not yet. Had an offer for the front bush installation of around 270 pounds, which let me hesitate since I already some very expensive carbon parts this month.
Furthermore my garage advised me not to change the rear bushes because of noise increasement (the original bushes seems to have some sort of oil bags inside which reduce the running noise).
