If you don't have the Factory Service Manual from the FAQ section yet, grab it. 
On page 3-25, it lists torque values there. This would be torque require to turn the pinion once it is tightened down.
Old Bearings: 10 - 20 inch pounds.
New Bearings: 15 - 35 inch pounds.
Trouble is, getting that crush sleeve to start crushing..... takes a LOT of torque...... So, tighten it down some, till the slop is gone, check rotational torque, repeat as necessary till you get it within spec. If you go over..... replace the crush sleeve, and start over again.
