I spoke to Dexter and they said there is a bit of a process for installing the spindle nut properly.

1. You will need to thread on the inner nut, rotate the hub, then tighten the nut to 100 foot pounds.
2. Loosen the nut to remove the torque, making sure not to rotate the hub.
3. Hand tighten the nut, then back it off 1/2 to 3/8 of a turn
4. Place the tang washer on the spindle and bend two tangs inward over the nut, This will keep the inner nut from turning while torqueing down the outer nut.
5. Install the outer nut and torque it to 100 to 175 foot pounds. Ensure that the inner nut does not turn while doing this. Bend two tangs from the tang washer over the outer nut to secure it.

Once all that is done you should end up with anywhere from .001 to .010 inches of play. This is also the recommended tolerance that Dexter suggested.
