All good points. That is a good idea. One option is I reboot the the side that has not cracked and re-grease.

Roll the dice? Safety wise or nuisance (getting stuck or having to redo the work) ?

I commute in the car so breaking down is not an issue. I will just get a tow. I hear what everyone is saying about getting some stock axles but it is just not practical. I don't have time to search junkyards or pay $200 more for some used ones. Also I think the whole idea of using oil instead of grease is a good idea as far as lubrication but far worse idea for longevity. I have never seen rubber being used to contain hot oil in a car. Anyone have an example? I don't have extra money to spend if the Advanced Auto axles will last a few years.
