Bought a used 04 ram and love it. Service is calling for driveline fluid changes but not sure how to tell what rear differential I have. It calls for different fluids if it's a limited slip.

It's a 5.7l Hemi full rear seat and long bed 4x4.

There was a paper tag on the axle near the right side wheel with the following numbers.
52069947AH
9.25 DR 4X4
3.92 TRAC LOC

Couldn't see a tag or stamped info on the rear pumkin. I did count 12 bolts on the cover though.

Does that ino tell me what type it is? If not is it encoded in the VIN? Hate to wait till the the cover is off to be surprised.

 

9.25" rear end, 3.92 gears.

 

You also have the anti-spin differential, or as some call it, limited slip. So you'll need to add the friction modifier when you add the fluid, unless you opt for Amsoil Severe Gear, then you don't need the modifier.

 

Take a peek inside to make sure the C-clips are good to go. Fluid change every 15K miles. See my guide and do it yourself. It will cost less than a tank of gas.

 

Word of advice, go with synthetic. Worth every extra penny.
