I purchased mine from an auto parts stroe. I removed one side and took the old bushings to a local auto parts stor. Thy came back with a bushings kit. The control rod was not part of the kit and I assume the kit wasn't from Freightliner, but the bushings were indentical. I found the easiest way to replace them was to remove the two control bolts on the sway bar on the sdie you are woking on. This allows the sway bar to drop down and clear the control rod. When one side is done, replace the two control bolts on that side and do the other side.
