    Ongoing problem, I didn't think the brakes would fix this problem, I only changed the brakes because the were wore pretty bad when I had the wheels off doing an inspection looking for the cause of this problem

    Change, drain and refill, the gear oil in the rear, and if 4wd, front as well. Use synthetic gear oil, and any recommended additive. Do the transfer case as well, if 4wd.

    The limited slip clutches usually groan when not lubricated properly and without the correct additive. It happens a lot in other makes and models. If they rebuilt the rear end and didn't separate the clutches and clean them they could very well be causing the noise. Other noises in transmissions have been eliminated by changing fluids as well. Just a thought on the maintenance side of car repair.
