We all know it doesn't take much to make our LSD start to slip, it's just not tuned very tightly at all. The factory spec for the 2000 Xterra is 138-180 ft-lbs. of torque needed to make it slip. I was shocked to see that the 95 Pathfinder with an H233b LSD has a 260-289 ft-lb. breakaway. I've seen them in action, they do work much better, I'd love for mine to be up there or even around 300 ft-lbs. (see my how-to in the backyard mechanic section)
Now, here's the shocker. The 2001 and 2002 Xterra have the same 138-180 ft-lb. spec. However, the 2003 and 2004 have a
PATHETIC 29-43 ft-lb. breakaway torque specified in the service manual. That's essentially useless, why even bother...
