Does anyone happen to know what the torque specs are for the front diff caps?

I guess I jumped into too quick assuming it was a dana 60, what front end do you have?

Im sorry yes it is a Dana 60. Pulled the pinion gear to change inner seals on the axle. Just needed to know what the specs are on the four pinion bolts.

That would be 80 foot pounds according to the handy dandy chart above. That sounds right, I just regeared my Dana 60 a couple months ago.

Thank you!

According to the -34, the final spec is 85 ft. lbs. Check page 6-53 for the start of the differential installation procedure.
