Hello, I'm Chris.I will do my best to answer your question fast and accurate using the info you have provided. Thanks for visiting Just Answer.
I do not 100% agree with all of the answer you got, you cant have a axle setup with a pinion nut torque as well as a crush collar. If you have XX.X axle you have a crush collar and you torque the pinion nut down till you reach a certain preload on the bearings. If you have a XX.X axle then you do not have a crush collar but shims which you have to change to achieve preload then you do have a pinion nut torque.
I first off need to know which axle size you have, 9.75 or 10.5?
