I was watching Tom, of Toms' Differentials fame (L.A.) set up a Dana 44 for a
cobra for me. He used a Snap-On torque wrench with a dial / tattle tale on it
when setting preload on pinion bearings. He stated this was the only reliable
way for him to set bearing preload.
Granted, they're expensive, but worth it. I also use that kind to work on CNC
machine internals.
