Rear Axle Specs?

[turnpike_cruise]

All, I am going to swap out the gears in my rear axle. I am looking for some specs that will allow me to dial this in. I have not been able to find them any where else.

Any and all help is appreciated.

I am looking for the diff bearing preload. I know what the pinion bearing preload is, but I need the diff bearing preload.

Also, I am looking for the PTTR (Pinion Torque To Rotate). I can get this information out of my existing axle for used bearings, but I am putting new ones in, so I need the values for the new bearings.

for the pinion turning torque, if you have access to a inch/lb torque wrench (beam style) you will be able to hook that up to the pinion yoke and turn at a constant smooth rotation and see how many in/lbs youll need to set the crush sleeve

i believe the existing preload will be good for the new crush sleeve
