Well, I'm bumping this because I'm now getting noise on the passenger side, the strut I just replaced. The suspension only clunks going down. I drove over some curbs (my neighborhood has nice rounded asphalt curbs that have about a 25 degree angle on the edges), and even when I was going pretty fast, the noise only came going down. It's a popping noise almost, like a sharp bang, similar to the pop the hood makes when it releases. It does it over very small bumps at low speeds, small bumps at higher speeds, etc, nearly any time the passenger side deflects. I think all of the strut mounting bolts are tight enough. I tightened the strut rod as much as I could with it in the car. Pinch bolt is tight, tie rod nut is tight and cottered, wheel lug nuts are all tightened properly. I replaced the strut, which I assembled myself, and the front wheel bearing on that side. No other issues, ride quality is firm and tight, handling is better than before. This noise wasn't here before I touched the strut, though. I can't seem to reproduce it by pushing on the fenders, even putting my entire weight on them and bouncing. There is a little bit of a noise that seems to be connected to movement of the passenger side motor mount when the car is rocked back and forth in park (i.e. pushed back until it stops, allowed to roll forward and pushed back again decently quickly). Any ideas?
