If this starts happening to a few people then I would think this would constitute a factory defect either in materials (bleeder too brittle) or workmanship (no anti-sieze on parts that are meant to be removed) and should be covered under warranty. Ryan, are you still under warranty, I see you have a few miles on your truck, but thought you might have the extended warranty. If it were me I would definitely look into a warranty claim. Even if you broke it, it is clearly defective. When I get under my truck to do the transmission/TC/diffs this weekend I am going to give my bleeders a try and if they break I will be at the dealer first thing Monday morning (truck is less than 1 year old).
