    Default Pre-load torque setting for Pinion

    Anyone have any idea of what the pre-load torque setting on the pinion nut is when changing the companion flange on an E34 big case differential?

    My memory isn't the best but I believe it's 137 ft-lb. I did mine (3.91 LSD) with the max my air-hammer could put out and used Loctite 262. I know my worn out air-hammer can't make even 100 ft-lb. Better to err on the low side. No problems 2 years/11k miles later, it's still quiet & smooth.
