They didn't put it on right. Super easy to fix. This way, the air vent points straight up and releases air pressure no matter the oil level. This is how it was designed. He had never had this problem reported to him. I'm not exactly sure why. The best I can figure is that my high speedo cable configuration, as a late production NP203, was not nearly as common as the earlier NP203. And in fact, my later model NP203 is generally stronger with the heavier differential carrier(instead of the stamped carrier) and chain setup. Perhaps he sees very few of these, even with his extensive experience.
I've since looked at a whole bunch of examples of NP203s installed on the trucks. Apparently, my rear output housing was native to the last two years. Before that, the speedo cable exited near the bottom pointing out towards the driver's side. Pretty exposed. The '78s and '79s look like mine, nice and high, out of the way.
