I had the click click on the rear as well and it was the bolt moving around lightly on the top of the shock when taking and releasing loads. I bought two 1/2" nylon bushings and put them on the outside of the bolt and then used my impact to drive them down and flatten them out so they act as a washer. When i put them on they fit inside the hole on the body(the outermost thin hole) on the top of the bolt and when i smashed it down with the impact it did a pop rivet kind of move and flattened on both sides of the metal to keep the bolt from moving around in the hole. Haven't had the clickety clack anymore.
