I also have an auburn LSD. makes terrible noises. that mixed with my whining Motive 3.90s, wow. my rear just sounds AWFUL. I'm not exactly sure what the problem is. I've used three different types of gear oil.
When the gears were first installed... conventional oil with limited slip additive was used. After being broken in I used Royal Purple's 75w-90 wihtout limited slip additive (which i didnt leave for very long). I am now using Lucas heavy duty 85w-140 with lmited slip additive. and it is NOISY.
