    Clunky vibration

    So I just replaced both front control arms because one of them was worn out, it was metal on metal for a few days. I still have a clunky sound and a vibration that matches it in the steering wheel upon braking or hitting a pot hole. I am thinking it is the struts, but I am not sure. I guess it could be wheel bearings but those were replaced last spring. It is only on the right side which is the same side the control arm went bad on. Any ideas? It sounds almost exactly the same as when the control arms was bad just not as drastic.
    I feel like a fish out of water, most times.

    Check to make sure the sway bar mounts aren't broken or damaged. I had the same problem, and it was due to a broken bracket where the sway bar mounts to the sub frame. It could very well be strut related though.

        What all did you replace when you replaced the control arms? Did you do rear control arm bushings as well? Could be upper strut mounts.

          I had the same problem with my Mercedes and it was the wheel bearings.

          As you can see with all of the posts, it can be anything that is attached to the wheel. Just make sure you take a look through everything thoroughly. It can be dangerous.

            I am thinking it might be a warped rotor. What does a set of drilled and dimpled rotors cost?

              Unless you really like the look of drilled rotors I think high quality blanks and fresh pads are the way to go. I just installed my brembo blanks ~$40 each from bma and hawk hps pads with fresh fluid and the difference is night and day.

                I have this exact setup, and like it a lot for DD/some track use.
