Unable to find mention of lubricating front wheel bearings. Have searched handbook on my GMC 2500HD D/A and can't find any mention of it. Am I going blind along with getting old.

They are unit bearings, and they are permanently lubed at the factory.

“Permanently lubricated at the factory” translates into -> when the bearings go bad it coast you big bucks to fix the stupid thing!!!!!!!!!! I understand $400 - $500 per side.
