I installed 5100's with moog fj springs recently. I used kyb strut mounts. I developed a loose squeak/clunk sound. I found both top bushings loose. The drivers side is worse than the passenger. What would cause this? I can see that both the shock boots have dropped too. Did the strut mounts fail? The top nuts are tightened down all the way. I can see there are no more threads left for the nut to go down anymore. Thanks in advance.
