The last time I had wheel and brake drum off I recall the axel appeared more like the 28 spline axle (oblong indented area) than the 31 referenced in the material in your link. Of course at the time I wasn't aware there were different spline counts. The tec who installed the axel seal said it was a 31 spline and put a seal intented for a 31 spline on it but from the material I would have called it a 28 spline due to the oblong indented area.Look at the end of the axle in the center. 31 spline will not have an oblong indented area in the center with a round mark. It will look like the picture in this sight toward the bottom. In case there was anything else you wanted to know!
