Well sense you ordered new ones I think its evident Ypu think the same as me... The amount of grease that is caked around the LBJ and surrounding area tells mee that this isn't a new fresh issue... Imo you are on barrowed time with those, as 02se stated dirt, water and other contaminants can get in there and cause damages that can not be seen. Those things look like they belong on a large truck with that much grease,.I'd be surprised if there was much grease left in.the joint or boot honestly. Change those suckers asap.
