Jack up the truck and try spinning the rear wheels to see if it makes the noise. I am betting it is a wheel bearing.

Speaking of which, how long do the wheel bearings last on nbs units?

There is no preset time but a lot of factors can limit how long they last.

Did you ever figure out the problem to this?? Mine is doing the exact same thing! Both back breaks changed along with wheel bearings and seals. Removed the e brake pads and it still does it. Only thing left would be to try new rotors or else that carrier bearing... No sure how hard that is to do or how much it would cost.

Thanks for any help,

Luke

Have you checked your tires for cupping (hi/low spots)? That will cause the sound your describing as well. Cupping will usually happen with your shocks going bad or are bad. Also not rotating them as often as you should.
