Hello, I'm Danny.
I've attached picture below of the torque requirements for the differential covers for your truck and I also the fluid recommendation. From what is looks like your front differential is a non-locking or open differential and the rear differential is a limited-slip differential. The best way to confirm is to call your local Dodge dealer and give them your VIN- vehicle identification number and they can check for your trucks equipment and options. Hope this helps and thanks for using 2CarPros.
