Ok i went from 2:73 to 3:73 and i installed it myself and there was pretty major whine in it, decelerating had a kind of knarling sound. I took it to dealer and they checked it out and said there was a bent spacer on the pinion, they put everything back together, little bit better, but still ALOT of noise and a very faint knarling noise. How much noise should i expect, i mean this thing HUMS when you accelerate at highway speeds. 60+ Could i be using the wrong fluid? Should i add the Rear end Additive. Thanks for all your help!

I think a little humming is expected but this is different than gear whine.
