Is it clunking or squeaking? My rear passenger side squeaked going over bumps especially in the winter. Probably a bad bushing. Haven't really listened for it since the Koni install last weekend.
Since installing my Koni's and I noticed if I push down on my hood and bounce my car, once I stop the struts will make a very subtle clunking noise but I assume that is just the struts expanding. It's very faint. I don't think I would be able to hear it inside the car.
