I'm helping a buddy install 488s in his Dana 30 and I am torquing the pinion to the spec of 200 ft lbs. I cannot find a spec for the rotating torque but checked it anyways and it's 160 in lb which seems insanely tight? Is there a spec anywhere?
 
Hey Roddy.....Long time! As Utah Jeeper stated, during the setup it's more about the rotational force rather than static torque. Unfortunately, if you have already tightened down the pinion nut to 200 lbs., you’ll need to replace the crush sleeve (collapsible spacer) and for the sole propose of safety, replace the pinion nut as well. If possible, don’t remove the pinion (or loosen it) from its current seat.
You’re going to need an Inch Pound beam style torque wrench. I will tell you that torquing down the pinion nut it will be difficult to start with and you will suddenly hit 12-15 inch Lbs. Just go a little tightening at a time and re-check your rotational force measurement. I did a write up on rebuild the D30 in the how to section and I briefly touched base on this.

Good Luck Bro!
 
Hey buddy I've been in hiding saving money for my rebuild:( maybe he was wrong and it's not a 30 bit it doesn't have a crush sleeve.? The only spec either one of us could find (likely not looking in the right place) was static torque
 

Is it an older Jeep? Sounds like a D25 or 27. An easy way to identify would be his axle has inverted "King Pins" (with bolts holding in place) rather than ball joints.
 
That would make it a High Pinion D30. I would need to look that up unless someone has a answer for you. I'll check when I get home tonight.
