Now take a look at their drawing and you will see that the inner bearing has no shoulder support next to the grease seal. Their drawing shows a best case situation that I have never seen. In fact, the drawings and tolerances confirm that there can be zero contact with the bearing ground surface, in my opinion this is a design defect. With the bearing pushing against only a sharp edge, the bearing adjustment is quickly lost. Those that only want to toss grease at their spindles have no clue.
That may be more of a "illustration" rather than taken from actual CAD drawings since I retrived that pix from Dexters service manual.
CAD drawing I would have expected to have dimensions and tolerances notations..
However, I am not exactly a fan of drilling the center out and then cross drilling out material where you want or need full strength.. To me, I would rather have 100% solid "meat" to work with instead of "EZ Lube" capability.. To me, it is a potential weak spot that can be bent or worse snapped off.
But, I get it, folks like "new fangled things" that are sold as time saving gadgets and not everyone like myself cares to get hands greasy..
I didn't buy my flatbed trailer because it had "EZ Lube" axles, it unfortunately was part of the deal so I must live and deal with them on one of my trailers.
If you must have one and must use it, just read and follow the instructions, otherwise you could face having to needlessly replace brake backing plates.
