Good to know. I have the same suspicious zerk on my CK2610HST front axle. Thanks,Well I finally unscrewed the offending front zerk, expecting it to be plugged. It proceeded to spew a stream of GC amsoil grease at me, obviously under pressure in there. Since this is red grease, and OE grease was green or brown, I know it has been taking grease all along. Somehow it does not vent any though, unlike the rear pivot. Still, should be plenty of grease in there until the next "official" greasing.
