I replaced my stabilizer bar end link last year. Today I noticed a clunking sound coming from the rear. When I checked the end link, the bushing and rod that mounts to the strut had slipped off the part that bolts to the stabilizer bar. The bushing was halfway out of the metal ring it's housed in. Opposite the threads is a short rod the bushing slides over it. There is nothing on the end of the rod to prevent the bushing from slipping off. I'm baffled as to why the bushing might have worked it's way off. I used vise grips to push everything back together. I figure as is, it will slip off again.
