Stock 10-bolt rear end is LOUD when cruising; what could it be?
I know this is a very open-ended question and for an accurate diagnosis, it would have to be seen/heard, but just as a starting point, when I am in 6th gear cruising at just normal throttle, the rear end of my car is just obnoxiously loud with a whining noise. I do have some loud tires, but I can distinctly tell a difference between tire noise and rear-end noise. My car has 55k miles on it and I don't beat on the 10 bolt. It hasn't been altered in any way and is a 3.42 stock car. The car is currently up for the winter but I wanted to get this resolved before I got it out in the spring. Any help would be appreciated guys, thanks

I'm no expert but I'd say your rear end is on the way out. Mine was doing the same thing 2 months ago before it went boom while cruising on the highway. Might want to start saving some cash for a new one.

i had the same problem, it was a horrible whining noise that happened at low RPMs mine was the carrier bearing thats was rubbing on the carrier housing witch caused my pinion gear to wear on my ring gear on the left side it wore it self a nice grove finally blew up on the street after i got my new tires.. but most likely its a bearing going bad causing your gears to wear funny
