2000 Silverado 4x4

Today I was doing the rear pinion seal on my 2000 Silverado 4x4. Since I was doing this in class as I am attending an automotive service course. Mitchell on stated that the moving torque of the bolt on the pinion should be between 48 and 84 INCH pounds... The teacher used my vehicle as a demonstration so two boys under the instruction of the teacher were torquing that bolt. They were yanking on that bolt so hard they literally moved the truck 1/4 of an inch over on the hoist six feet in the air. Since the teacher is always right at about 300 ft torque pounds solid and 60 inch pounds moving oont he pinion we put everything back together.. Problem is the driveshaft wouldn't move. It took two guys again to yank that thing into motion, still super tight moving it. before we took it apart I could physically turn my driveshaft.

So what do we do. Well I'm taking it apart cause it made one hell of a god aweful noise when it started moving in gear.

Now that I have put it back together at much less of a torque. I could physically drive home atleast. But the real question.

Did they completely total the crush sleeve? Could they havewrecked the bearings in any way? Is there anything now I should be worried about, refferences on why it being that tight was so bad?

Please Help. Thanks.
