It seems lately the limited slip on my truck has lost its strength. I know it is supposed to be gear type unit that should act the same all the time and need no additives. But the handling has been bugging me alot lately when its slippery. I feel comfortable withthe back end of my truck sliding ut now its not a consistent feel. it will go from a nice easy drift to almost stoping and wanting to go the other way with no ryhme or reason.
