Okay so there is a 100% all stop to this. By removing the pinion I lost all references needed for re-assembly. In addition to this ZF does not publish the pre-load needed so that the crush sleeve can be correctly set. Also a crush sleeve like a axle/pinion seal is one time use only. Re-using it again and you run the risk of crushing the bearing in the race. No thanks.
ZF nor dodge sell crush sleeves as from what I can see on store.mopar.com. I have two options. Use another differential that is brand new, drain, pull the entire center section out, remove ring, go to town.
I have another option.
@zhc kindly sent me a differential out of the charger, it was in good condition when removed. Drain, rip out center section, remove ring, leave pinion. Prior to this measure backlash. Would avoid pinion issues.
I have reached out to
to see if they have a solution for Hellcats or something that may work. Right now eating dinner so I will take my measurement tools to it in a bit to get dimensions. Also a very good option to the crush sleeve, you can torque to hell and it's not going to become useless.
I have a sneaking suspicion is that ZF/Dodge built these to be not re-pairable.
