Missing zerk

Who thinks up the names for these parts? Not sure if this is the right forum but here goes. While greasing my Al-Ko Ultrulube bearings on Al-Ko axles (now owned by Dexter), one of the "zerks" (the nub the grease gun goes on) is missing....don't know how, but it was there last year. Anyone have this issue? Easy fix or does it require some work? Thanks for any info. Camp on!
  • Some are pressed in others have threads on them, is just the top broken off, has the pressed in part completely gone, has the old one come unscrewed? Will need more info to go any further but you can buy them @ any parts store, just need to know the thread size or diameter of the pressed in ones.
  • You can call them Grease Fittings or Alemite Fittings if you don't like Zerk Fittings.

    Or, like many of us, you probably have your own name for them. Especially when they don't work or break off. ;)
  • feet has your answer. take a real good look at it , even check a good one .there threaded or pressed into place.
  • You would be better of if they were all missing! Blindly pumping grease into a hub is OK for boat trailers that go in the water, however you are much better off to just repacking the bearings every two or three years. While doing that you can check the brakes.

    Absolutely!!!

    I made ours inaccessible by putting hub caps on with no hole for a grease gun. 12,000 miles, 12 months is the Dexter recommendation for disassembly, inspection, cleaning and repacking. That's a bit too conservative for me so I use 12,000 miles or 24 months though historically we do over 12K miles a year so ............
