Thanks for all the help so far. There's a great write up on Ford-trucks.com that seems to be the standard. It's interesting that this thread also shows up on a Google search about 9" rebulding.
Something is out of order here.... there is no way the crush amount for the brg cups in the torqued up caps is 0.025" as you mention here... 0.0025" maybe ( In my experience its usually possible to adjust preload 'after' torquing brg caps--- With 0.025" crush I doubt that would be possible.), either the caps have been swapped from side to side or they have been milled/swapped from another housing. Looks like you need another housing with correct caps etc.

That said it is normal for the preload of carrier brgs to increase slightly with torque of bolts as the thread angle of the adjuster nuts induce this.
