I'd bet there is a bump on the threads where the washer locking tab sits in the groove. The set-screws may not have been out enough when you loosened the outer nut or the parts were just rusted together. I'd tighten the inner, then run the outer nut back and forth like Patrick said - without the locking washer in there. Ditto the tapping lightly with a hammer when it feels snug on the threads.

OK, I'll try that stuff tomorrow or monday when I get a chance to get back at it.  It seems to get tight at about the last third of the threads, that's why it seemed odd cause the outer had to go over that.

Kinda silly in a way that I'm even going through it.  It's just for the experience really.  But, I'd surely rather be trying to figure it all out in my garage than on a trail or in the campground.

I forgot to update this.  I managed to get the nut off, I had to just force it past a buggered spot.  The outer nut was galled up causing the problem for the inner nut.  Anyhow after what seemed like eternity with a tiny file, I think I salvages the spindle.  Ordered a new lock nut set, the outer was just too screwed.

Meanwhile, the passenger side come off and was completely disassembled in about 10 minutes.

So I moved back up front and started putting everything back together.  Despite all my efforts I couldn't get the driver spindle nuts to go back on freely, so I ordered up a new spindle.

Anyhow, everything is going back together but I have questions / issues with torquing the spindle nuts.  Pretty much everything I read says to tighten the inner nut to 50 ftlbs while spinning the hub then back it off 1/4 turn, put the lock washer thing on and the outer nut torque to 120+ ftlbs.

Problem I'm having is everything also says the hub should spin with little resistance, by time I get it to 50 ftlbs it's not spinning anymore by hand, back it off 1/4 and it's better, back it off slightly more and it's great.  THEN I put the lock washer and outer nut on, when I torque the outer down I can turn the hub and rotor by hand but it barely moves.  It certainly has a lot more than drag.  I can't imagine that's right.  Am I missing something or not doing it right or???????

I feel stupid for even needing to ask all these questions, but I've never messed with any of these style axles before.

Any suggestions from you hub type axle experts?

This may not sound very precise, but the 50# starting point is way too tight.  I have always tightened until the hub until there is enough resistance to turning about equal to a pound or two of torque, then backed off.

From Warn instructions: torque inner nut to 50# while rotating wheel back and forth, back off 1/2 turn, re-torque to 3-5#. Install lockwasher and torque outer nut to 125-150#.

I don't know that my torque wrench will do 3-5#, I suppose I could do the conversion for inch pounds, but then I'd need a 1/4 - 3-8 adapter and a 3/8 - 1/2 adapter.  So just by hand on the socket would probably be fine.  Basically the first nut is just seating the bearing all the way right?

Just to clarify, once the second nut is on it should still spin relatively freely?

Also is the inner part of the actual hub lock supposed to touch that outer nut?  I had it on there at one point and it seemed ok, but then the lock part was hitting the nut and I couldn't get the circle clip on the shaft, like it wasn't going in far enough to access the groove on the shaft.

Yes, it should spin freely but not rattle if you try to shake it

Sounds like you are saying you can install the large snap ring but can't reach the groove on the axle for the small snap ring. Just reach around to the U-joint and push the axle out a little. It should "float" somewhat.

Yeah, tried that it was more than a 1/8" from being able to see the groove.  I've got a couple of hours today then maybe again for a bit on Sunday then I won't be able to get back at it till the following weekend.  I'm thinking something inside there is wrong.  I'm gonna pull it all apart today and double check everything and try again.

FIGURED IT OUT!!!

Note to self (or anyone else)

If you slide the hub and rotor on and the outer bearing pops loose, make sure it didn't flip over.  Because, shit won't work if that bearing is backward.   :shaking:
