Differential replacement instructions

Hello,

It will depend on which rear differential each truck got equipped from the factory.
As they use couple of different types of rear differentials on both of those trucks.

The best course of action would be to call the dealership with the VIN and find out what was factory equipped for each one and go from there.

Please let me know of any questions.
Thank you.
