I am trying to find the cause of front end noise on my 04 grand prix. It happens when driving over small to medium bumps, when both wheels hit at the same time. It sounds like something knocking under the dash.
I replaced both lower control arms with moog problem solvers but that did not solve the problem. I need help because it is driving me crazy. I am sure other gp's make the same noise so any advice would really be
appreciated.
