The message to the rest of us, who are cringing at the thought...GREASE the tag axle fittings like there is no tomorrow.Every time, all the time, and replace or otherwise force to function zerks that won't take grease.One of the inherited poor maintenance items from the previous owner. Famously ignored by the grease gun for far too long. Keep putting grease into all the zerks until it comes out someplace else. Check the maintenance manuals and be sure you have found all the zerks that are SUPPOSED to be there. Re-instate those that are missing by whatever methods necessary.An excellent justification, not an excuse, to purchase a good quality powered grease gun.You want your grease gun to work, all the time, every time, not become another source of work. Cheap ones will pay you back in not greasing, just passing wind...Purchase your favorite grease by the case, and keep swapping cartridges as they empty. I prefer a grease with some colour, as you can tell fresh from older more easily as the old gets pushed out of those places that that occurs.A blue valvoline product, suitable for the purpose, is my current choice, always available at the local Tractor Supply.Watch for sales and buy a few more cases, you'll use 'em up around the homestead.Those busnuts who get tired squeezing a manual gun, don't do enough greasing.happy coaching!buswarrior
