I'm glad that my suggestion on 3/26/17 was of use to someone. You did a fine job and that is exactly what I had in mind.
I agree with your maintenance schedule as well. The grease fittings have no place on any axle that will not be immersed in water. Since the spindles often have poor finishes and tolerances, it doesn't much matter if the seals are single or double lip, they both can leak.
Look at where the inner race contacts the shoulder on the spindle. You can check the contact area by using layout dye or a magic marker. 3500lb axles have little surface area and that leads to burrs and loss of bearing adjustment as the shoulder gets malformed. When a seal is pushed over the sharp edge, it is ruined as it is installed.
