Pinion nut torque spec?
How many ft. lbs. should i torque the pinion nut on my coil spring 12-bolt rearend? I can't seem to find it in any of my manuals. Or is the torque spec different for each rearend?
Thanks for any help.

There is no tork spec per say on the pinion nut on a 12 bolt. With the carrier & ring out, the pinion nut should be tightened enough to crush the sleeve, & give about 8-10 inch lbs rotating tork on the pinion(used bearings , & oiled). if you have new bearings, the figure is a little higher(about 12-15 inch lbs). The books will show a higher figure for new bearings.......but the driveline shops will run them a little looser to prevent "blue bearings". good luck.....crazy AL
