Hello guys, I have a 2011 E93 335i with 120K miles.

I have M-sport suspension, and my struts were completely blown. I bought Bilstein B8 struts and replaced all 4. When replacing the struts I also replaced all the hardware / rubber pieces.

Immediately after replacing the struts I started hearing a TON of metallic pops and clanks, so I thought it was my control arms and the new struts were just transferring the energy more into the control arms. So I replaced all the control arms except the one that adjusts the alignment. They were mostly OK except the real small one (tie rod?) as it was completely shot.

Now there is definitely less noise, but I’m still hearing a lot of hollow-ish sounding metallic pop / clank noises when going over smaller bumps / cracks in the road.

Is it possible I didn’t tighten down the main top bolt enough? How tight are you supposed to make those? I wasn’t sure how far you tighten them, are they supposed to be bolted down all the way? Or what else could be the problem here?
