While replacing my rear suspension (stock height), I noticed that the Moog sway bar links had incorrect top nuts. I called Moog to verify, and the tech said it looks like they are all shipping with the wrong thread. The correct thread should be M10x1.25 lock nut, and the one that came in mine were M10x1.5. I was able to find the right lock nuts at the local hardware store, and the tech also said that either the nylon lock nuts or the thread-deforming type will work. Just wanted to put this out there in case it saves anyone some time.
