Hello all. So I just got done pulling motor, trans, replaced clutch, all gaskets and so on. During the process I saw the rear pinion seal and/or cover leaking. So I went ahead and replaced the pinion seal and cover gasket. What I can't find anywhere is what torque to set the pinion nut so I can continue on and drive my car. It's the last thing I need to do. It's the borg warner 9 bolt posi rear axle with disc. Thank you in advance.

 

Just torque it to 150 ft/lbs with some threadlocker. The torque setting just has to be tight enough to not come loose but not so tight that it crushes the sleeve and changes the pinion pre-load. You can't go by any specs because the specs don't give a torque value - specs are to crush the sleeve and then measure the rotational torque (drag) on the bearings with no carrier in the diff housing, etc. You can't do that if you just pull it to replace the seal so just put it at 150.

Ok thank you. I know gm 10 bolts can be done that way but wasn't sure on the 9 bolts tried manuals and Google and some threads here but no straight answer. I put money in the car and don't want to screw up a torque on a pinion nut lol.
