Here is where the seal and spacer should sit at the flange of the stub shaft.
Then carefully slide the spindle over the stub shaft, making sure not to mess up the seals you just put into place.
Then place the brake caliper bracket on the knuckle studs and tighten the nuts to 30-40 lb-ft (From Pirate4x4.com) or to 65 lb-ft (From Pavementsucks.com). I'm leaning towards the lower spec ~35 lb-ft. These are the only sources I can find with this spec so if anyone knows for sure I'm all ears. In the end it will look like this.
Note that I am doing an 8 lug conversion on top of my axle rebuild so your spindle and caliper bracket will look a little different but the process is exactly the same.
I didn't get to the wheel bearing and hub/rotor install yet but hopefully this Fri or Sat.
