Gear Oil Question

[DHess]

First thing I did when I brought the '03 home was check the fluid level in the differentials. Using the "little finger bent at the first joint" measurement, the leve was ok but not where I like it. Took it to the dealer and told them I wanted both differentials, transmission, and transfer case filled to the fill hole. They put a quart in each differential and a quart in the transmission. The thing is that they put the same lub in all three places. They used part number 4874468. The owners manual says 4874464 in the transmission and GL-5 SAE 75W-90 Synthetic in the differentials. Anybody know if these fluids are the same or compatable? Thanks!!

This is the straight scoop on the differential lube.
