Dexter EZ lube is nice in theory but it bypasses the opportunity to inspect the bearings and races, brake shoes, magnet, and attach hardware... I don’t and will not use on my fifth wheel. Hand pack old fashioned way and eye balls on the parts..
That said... Dexter produced this video of how to grease the bearings on a Dexter axle... note it is an EZ lube system yet they are doing it the tried and tested “old fashioned way”
