Well I can tell you that lapping these axles and hubs was accomplished in the past when they have sheared the keys and spun the axles within the hubs. Of course that wasn't done in the way of lapping as hardtimes means it. So my thought was to built up the low spots with JB Weld, file it is true as I can get it and then torque the hub nuts to 125 pounds, thus putting most of the holding pressure back on the taper rather than on the key. I believe that I have done that, and tested it to see if there was any sign of the axle slipping within the hub by going from forward to reverse while listening and feeling, with the seat of the pants, for any sign of a click or feeling that either took up slack in going through the change in direction. I'm not 100% sure if my torque wrench is accurate, but with my impact wrench I took the nuts to the next cotter pin hole past the 125 mark and torqued again to see where it clicked. It had"t clicked at 140#, so I guess it is good. After my next trip, I may pull the hubs and see if things appear to have changed at all. JB weld out of place, that sort of thing. It did only stay filling the large grooves as the minor grooves din't hold the JB against my filing. Should have used 220 sandpaper and water probably an all day task. Next time.
