Default Knock from rear under heavy acceleration

Hi guys,

Been having some wierd knocking noise coming from the back of my car lately. Haven't seen anyone mention something like this on the boards yet. Under normal acceleration I only hear the slight rear axle ticking which I have yet to take into the dealer to fix. However, when I accelerate faster, I hear a single knock which sounds like its coming from one of the rear wheel wells. I am also running a Cusco LSD, but when I first put it in, my car did not have such noises. Anyone else experience this? I am also fairly certain there are no loose parts in the back.

Thanks

bump, still having same noises. I've checked everything out visually and also changed the diff oil over this period of time. Anyone out there having any issue like this? I forgot to mention that this happens only when accelerating from a stop or immediately after i change gears.
