Just a bit of history for filling the AAM 11.5" axle that came out in the new redesigned 2003 Dodge trucks.
Dodge first says 11.5" Rear: 1/2" +/- 1/4" (Total of 3/4" below Fall hole) which my then new '03 2500 Dodge/Cummins came with. Some where around 3500 miles the AAM started whining so I pulled the plug and found oil 3/4" down from the fill hole. I did a 1-800 to AAM and according to them Dodge was using the wrong fill line info and they were advising Dodge truck division of AAM proper fill recommendations. I added most of another quart to the axle. Later Dodge corrected their screw up.
But it left me with a whiner.
Dodge says to pull heavy for 10k miles or so and report back. The whine was gone by 35k miles. The truck now has close to 340k miles on the same AAM axle with 75w-140 Redline rear lube change every 75k-80k miles.
Best axle lube ?? just like our new gen LDTs...there is no best.
