It wouldn't hurt to pull the rear end cover and look over your ring gear and spider gears. If the oil has shiny specs in it you know there is a problem.
When I broke 2-1/2 teeth off the ring gear in my old 84 Camaro a few years ago, it popped when I took off then howled at higher speeds. Not an uncommon problem with 10 bolt 7.5" rear ends.
