MBenz, Yeah it's those parts. Sometimes they are also reffered to as door straps. I figured there might be a difference between the fronts and reas, but why doesn't anyone list the difference? I know that the door checks won't completely get me the "THUD", but it's a start. I figured since these have lost their stiffness that this may be contributing to the "clank" sound. I do plan on going through each door and tightening everything down, but I'll have to wait until it gets above 35F degs. outside. There is nothing like smashing your nuckles when there real cold. My doors do have the tar plates, but I will probably spray some more sound dentaning in the doors to help it out. I just want the doors to get that typical MB stiff solid feeling back in the doors.
