ONCE YOU BACK OFF THE PINION NUT YOU MIGHT LOOSE YOUR BEARING PRELOAD, I WOULD CALL IT SAFE AND REPLACE THE PINION SEAL AND A NEW CRUSH SLEAVE.

tourqe what to? if your talking about the pinoin nut, you need to put 8-14 in pound of preload on the pinion bearings, the main caps are 60 ft. pounds

you can not set pinion preload unless you also remove the axles and the carrier with the spec you are giving. Plus the main caps are more than 60 ft lbs..
