Car developed a bad squeak, and started to feel funny at highway speeds. So removed my aftermarket lower control arms, and put the factory ones back on. The bushings on my aftermarket ones were completely destroyed. torn to pieces, worn out, looked like hell. Hell on the passenger side, the rear bushing, there was barely a bushing left. Guess road salt is in the enemy of those bushings. they lasted about 2 years.
So squeak is gone, and car feels fine.
