Theres nothing wrong with the LSD itself. Mine works just fine. Its just the clutch pack retaining clips in the LSD that sometimes break off and get chewed up by the gears and then the oil gets contaminated from the metal particles. Mine had the issue but came out fine

 

i have 3.92s with an OPEN diff. and it sucks!!! i spin the pass tire at every light when the ground is wet. and most of the time im not even trying to!
