Well to start out heres the list of suspension mods done to the car, its a 98 btw
Kenny Brown Sub Frame Connector
Eibach Springs (lowered one inch)
1LE Anti-Sway Bars
Prothane Bushings & Endlinks
BMR Lower Control Arms
I had the upper/lower A arm bushing changed back to stock since everyone that I talked to said they would most likely be the reason for the noise. Its hard to describe the noise, it doesnt sound like a metal clunk kind of noise its more like a squeaking noise. Anytime I go over a bump the car makes a loud noise, reminds me of my old Chevelle when I first got it. So I really dont know what I should change or what it could be?
