Universal joint (one) went while towing horse trailer. Had it replaced, fluid changed. Lasted only 2 years and did again. Lasted 2 years and this time replaced all joints and the bearing connector with grease fittings so could keep greased instead of GMC sealed fittings. 2012/3 replacement joints were making a clunking sound in reverse and when starting off in first gear.
