What with the changing the rear end lube at 15000 mi.??? are these new trucks different the my 98.5??

 

Dodge changed axle manufacturers in 2003, but I thought the severe service was about the same on the old ones?

 

I think most people on here will agree its is way to often but still do it as long as the warranty is still in affect. I drained mine at 17,000 and the oil looked new with no sludge in the bottom.
On a different note, I went to the dealer asking the amount of oil for my rear end. The parts guy proceeded in telling me I had a DANA axle and that I needed the lmilted slip additive. I tried educating hime since the AAM axles have been in service on the new trucks for over 2 years now. He refused to belive me. Even the repair manager didn't know. He did pull the book out though and I showed it to him in black and white. At least he accepted the facts with a little humility. Never take the dealers word on your truck as fact. Most of them seem to be clueless about they products they are supposed to be experts on.

 

You'll need 4 quarts of oil. I changed mine at 30 K and it looked like new. I do a fair amount of 10K# 5er pulling.

I used Mobil 1, 75W90 as I recall.
