What differentials do I have?

[RideSlow2004]

From the Amsoil fluid capacity site: (it is a 3500 SRW)



(Front is only shown as option code DJQP 5,200# Front Axle)



Differential, 9. 25 AA Front... ... ... . 4. 7 pints

Differential, 9. 25 AA EL Front... ... ... . 4. 3 pints

Differential, C205FD Front... ... ... . 3. 4 pints



I am pretty sure I have the trac-rite 11. 5 AA rear



(It is listed as option code DSA Anti-Spin Differential Rear Axle)



Differential, 11. 5 AA Open Rear... ... ... . 8. 9 pints

Differential, 11. 5 AA Trac-Ri Rear... ... ... . 8. 5 pints

If I remember correctly, it would be on the sticker on the inside of the glove box door.

will take a look, thanks. Front had AAM stamped on the inside of the cover, didn't get to the rear yet.

I wonder if the EL on the front designator refers to electric switching of the transfer case. I selected the manual lever for the transfer when I ordered the truck. I put in 4. 5 pints, and the fluid was just below the fill plug, maybe less than 1/2 ".
