It is intersing that you said you have a Detroit Truetrac. That is how I learned that different viscosity oils can allow different levels of noise to either be heard or become nondetectable.I had Detroit Truetrac that was making a bit of noise and by changing the fluid to a thicker viscosity the noise went away. I had originally started with 75-90 synthetic, and ultimatley went with a 80-90 conventional.
While Trachtec\had nothing bad to say about synthetic gear oil, it was their suggestion on my Trutrac to change back to a thicker convenional oil which did eliminate the noise I had.

Thanks for mentioning that, I went back and checked the receipt from my Trutrac install,and they put 80w140 in the axle that is much heavier duty than the 75w90I provided to them, (they charged me like 6.95 a pint which was ridiculous). I didn't take into account what the Trutrac might need.
That might be it right there,as it doesn't whine at a low speedbut it does when the speed gets up there, which I'm sureis pushing all the partsa little harder. I'll dump the current fluid and trysome heavier stuff to see if that doesn't do it.
