pinion
2000 f 150 7700 series, i was going to change the pinion seal and after changing it i went to look up the tourqe specs, well on this rear end i was supposed to record the specs while breaking the nut loose , the tourqe is specified some where between 20 and 40 inch pounds, any suggestion on what i can do to keep from over or under tightening my bearing?

I usually scribe the nut and pinion before removing the nut. Then I reinstall the nut till the nuts scribe just barely crosses the pinions scribe.
It should take roughly a minimun of 160 ft/lbs torque to tighten nut before reaching the scribe.
I reread your post and see you've already removed the nut so the scribe I use won't work. sry

How much torque it takes to tighten the pinion nut, and how much rotational torque you need, are two seperate things. Since you did not take a rotational torque reading, you can probably still get close enough. You are dealing with a crush sleeve in this area. It may take 200 pds. of torque to get all the play out of the pinion, but that is not what is actually pushing on the bearings. Tighten it down until you have no play in the pinion. Then keep checking rotational torque until you get to 35-40 inch pds. You should be good.....or close....good luck...

Hold the yoke and tighten down the pinion nut until all the play is out of the pinion...go slow as it gets close...don't back it off. It may take 150-200 pds. to do that. THEN..while not holding the yoke....wheels off the ground...,.put your inch pd. torque wrench on the pinion nut. Now...rotate the whole assembly....that is where you want the inch pound reading. Then you hold the yoke again if your reading is low and crank down the nut a snitch and recheck....
