Ok, so this is the first time I've seen a straight axle shaft from a 4x4, or really any vehicle in at least 20 years, so please forgive my ignorance.
First thing is whether or not the pitted and "worn" looking section of the shaft near the hub is "normal" or if it's a problem where something is wearing wrong?
Secondly, should I clean up the gears on the hub side and regrease with some marine grease or ???
I will be pulling this stuff back out in a couple weeks and doing new ball joints, but if I can get some advice/insight today before I do anything unnecessarily stupid I would be most grateful.
