Well, After much research on TDR, I found out that American Axles call for a 75-90 Synthetic that is coded as MOPAR #05102232AA. Thanks for all the help on here getting those #'s for me. Well, I went back and looked at my repair order and they installed Part #

4874469. . when I called them, they said it was Synthetic 75-140. Which we have determined that is NOT what is to be used in these American Axles. The parts gentleman said he had " No clue" that is what DC called for... how many trucks out there are running the wrong oil????? He said they don't even stock the correct Lube. . has to order it... I think I'm going with AMSOIL 75-90. What do you think??

I would run what is reconmended. I changed it at 1K miles. I am running Amsoil 2000 75-90. 13K miles no problems, also filled it to the fill hole.

Thanks, yes. . there is a post on here somewhere that I printed that is directly from American Axles. . They do NOT recommend the 140 for various reasons. They actually produce their own special oil for the rear axle. MOPAR assigned it the code I put in my first post above. I do tow a lot, and am sticking to the Recomended weight. The 140 is for twoing with the old Dana Axle as I understand it. Dealers are just stuck in the old days. . LO(LOL
