Hey everyone, new guy here from Arizona.  I got a question about my 2000 Nissan Frontier.  I have always had a little slack in my drivetrain, and what I mean by that is when the truck is in neutral, and the e-brake set, i can twist my drive shaft a little bit in both directions.  I assume a few degrees of movement is okay.  But since i installed a Loc-Rite locker in my rear end, it has a bunch of slack, like around 20 degrees, enough that I can feel it everytime I shift.  Is that the locker?  Or the ring gear?  I never unbolted the ring gear from the carrier during the locker install, so I dont think thoses tolerences are messed up.
