    Clunking Front End

    Within the past few months I have replaced front control arms, ca bushings, shocks, and shock mounts. Yet I still have this hardcore metal on metal sounding rattle/ clunk coming from my front left corner. I was convinced it was the shocks but I just replaced those and the mounts last weekend, and the sound is still there. The car is on cut H&R sports (one coil was cut) so part of me thinks it might be those.. but only the left passenger side makes the noise. What else could be causing it? Tie Rods? I don't know much about suspension so please forgive my ignorance, just help me fix this so I don't go nuts.
    Thanks

    Check the sway bar bushings and links and have a good look for loose fasteners or parts.

      I just changed my oil pan gasket and noticed my passenger side rubber engine mount was split at the top, the metal left the rubber. Also could it be a strut?

        You need to replace the motor mounts, and I'll bet the transmission mounts aren't in much better shape.

          I have brand new engine mounts and trans mounts as well. I will look into the sway bar links! Thanks

              Check the strut where it screws into the shock housing...

                I have new ca bushings, and are you guys talking about the threaded collar on the top of strut housing, I tightened it as much as I could.
                The noise is only coming from the left side.

                  check the sway bar end link like Jim said. Other than that I would check two things. Check that the steering rack bolts are nice and tight as well as all the front subframe bolts.

                    Thanks guys, it's really driving me nuts. Ill try look into it tomorrow.
                    For the sway bar links, I'm guessing just make sure there isn't excessive play in them, is that right?

                      is the clunk when you hit bumps, when you are turning? we need a little more info.

                      if you have a little wander on the highway and a clunk while turning i would say tie rods, or strut bearings.

                      if its just over bumps it could be CAB's, ball joints, shocks, or sway bar end links.

                          I do have a bit of wander, I figured it was just my shitty alignment. And the noise only happens over bumps. I've got new shocks, shock mounts (bearings), control arms, and cabs. What should I check for with the end links? Everything looks tight from under the car.

                          That has been the cure so far.

                            jack the car up, pull the tire off and check the links. Im guessing one is either broken and not connected at all or VERY loose in the control arm or the sway bar itself. I had one break on me and it did the very same noise.

                              do you still have the bumpstops on your new strut assemblies?
