Check the manual, I think Pinion torque is something close to 450#ft. My 450 D110 is 830#ft......

Is the trans mission in neutral?

A dana 80 is 450ft#'s the sterling 10.5 I'm not sure. what ever it is you also need to adjust it according to the preload on the bearings, and the 10.5 I believe uses a crush sleeve instead of a thrust washer. so you need to get back to were it was or barely a little tighter, those are made to only be used once really.

With a crush sleeve there is not final torque, just a pinion bearing preload measurement.

Sounds like you have over tightened it and now will need to have the crush sleeve replaced.
