old topic, but i'm getting ready to replace mine...spoke to my old man on this, and he's a 16 year master tech so i trust what he says, he agrees that you don't necessarily need to torque it back down to specs, but like everything else it ensures that you get a good seal, that you don't bend/break the new one, and so on...

yeah, it usually works that way...but when in history has made a quality seal or bearing! especially pinion seals and wheel bearings!

If that's the case, you can just multiply the number of lb-ft. by 12 and that will give you lb-in. measurements. 1 ft-lb is 12 in-lbs.

not if you are using an impact to tighten it. if it was inch pounds i could tighten it with a wrench, but i cant even turn it will some impacts.

The procedure is to tighten the pinion nut in increments until the sleeve is crushed the right amount to give the correct drag/preload on the pinion bearings. If you tighten the nut with a rattle wrench to some random torque, you will have no idea what the preload is. Taper roller bearings require a narrow range of preload for long service life. Too tight or too loose will shorten it.
If the pinion bearing(s) have also been replaced during the repair, then a new crush sleeve must also be installed before setting the drag/preload. In either case, the pinion nut should be replaced.
