Follow up.
I was going to buy a whole 1994 explorer for parts and a project later on, but it was too far gone for me to be able to do much with it once I got to looking at it. Turns out it had a manual hub (one was missing), even though it was push button 4x4. I ended up pulling the spindle in the guys driveway and it looked identical to mine, minus the ware. The spindle nut was a bit thinner than the one off my ranger though. I was hoping to replace mine since the little nipple is almost wore off. I reused my thicker one. It also had the thick splined washer instead of what I have, a plastic spacer between two thin washers, one being splined. So I used the thicker washer instead as one of my small splined washer is busted.
I replaced everything from the spindle up, minus the calipers and hubs. I think I may have squeezed one of the caliper pistons in to far and blew the seal, so I'll be replacing one of those tonight. I even picked up the o-rings for the hubs this time, so everything should be sealed up good.
Drove about 50 miles last night as a test, and then a 100 mile trip to work this morning. Everything is nice and smooth so far. There is a soft metallic rubbing noise on the passenger side at low speeds, but i think I may have bent the shield to where it's rubbing on the disc a bit.
So other than realizing this morning that I forgot to clean the new bearings before packing them, I think it went pretty good.
