So just a few days ago I changed the rear struts and mounts on my car, and it's still making that god awful thunk/clunk noise that a bad strut makes. It only happens when I go over bumps. I had my stepdad push up and down on the bumper to see if it made the noise and it did but I also noticed that the rubber grommet on bottom of the upper assembly moved. Is this normal? Anybody have any idea what the problem could be? Please help because I'm dumbfounded. :confused:
