I just put BAT springs and Bilstein struts on the car. The strut mounts seemed fine, although I'm not quite sure how to tell if they are bad or not, but they didn't make any noise before the suspension was changed. I also have a BAT sway bar and just had the subframe boxed as well..although i've had the bar on there for about 3 years. I relpaced the endlinks about 3,000 miles ago. All the other bushings and what not seemed alright. This whole thing seemed strange...just because the noise suddenly appeared after I had the suspension work done.
