I have a 2010 cobalt ss and recently when going over anytpe of bump theres a constant rattling noise from the rear on the driver side and i cant figure out what it is i did change the shocks but that did not help
2010 Lt owner here, same issue only its the rear passenger side. Just started making the noise after I had both rear springs and shocks replaced. Stupid me took it to the dealer thinking they would find and fix in no time, 4 hours and $211 later the rattle/clunk still there.
