I"m the one that actually does the oil, filter, and grease fittings for that very reason and it happened so not sure and considering i've been doing this on all my vehicles for a long time i would say it's a defect. Plus after reading other threads on this and what i noticed it makes sense...the bar was twisted while just sitting there and i can see that can then pinch the rubber over time. The rear grease boot is already showing fractures in the rubber as if it was 15 years old. I have a 1 ton 25 year old truck that doesn't even show those signs. The rv lives in california weather and it is stored inside when not in use.
