Since it was so nice out tonight, our first cool night in many months, I decided to throw open the garage doors and get to work on my axle.
A little back story on this axle. I bought it 6 or 7 years ago. It came out of a 1978 FJ40 that was being parted out. It sat in my open carport for a couple years before I moved to a house that had a garage and then sat in the garage for a few more years after that. I bought it with the intention of rebuilding it and installing it in my 68.
I got started tonight with taking the calipers off, both the calipers and rotors will need replaced, and got one of the Warn hubs pulled off. I had read that this is a messy job, and I can say that it is indeed messy.

I will get the other hub pulled off tomorrow night after work and will then get them cleaned up.
The only thing that seemed odd to me is that the large nut, you can see it in the attached picture, is actually loose, is this normal?
I do have one more question about the knuckles. I haven't measured the preload yet, but as I move them through their entire turning travel, there seems to be something of a detent in the middle, or where they would be if the wheels were straight. Is this "detent" normal or is there some wear in there that I need to deal with?
