[QUOTE="psduser1, post: 1185223, member: 735"] Ok. Generally speaking, a "locker" keeps both axles tied together, locked, until forced to unlock. A "limited slip", aka factory locker acts as an open differential, until forced to lock. Berman kind of said that a few posts back. That's the basic difference between a limited slip and a locker. An open diff allows the inner and outer tire to travel at different speeds as the vehicle moves through a turn. A locker, trying to keep both axles moving at the same speed, will "push" the inner axle, and tire, until tire/ground friction overcomes the lockers preload. With a newer, tighter unit, it'll force the inner tire to chirp, noticeably. As the locker wears, this release is more gradual, but it still happens. During the preload stage of this cycle, before the locker releases, the inner tire is traveling the same speed as the outer tire. However, since the vehicle is turning, the inner tire is not travelling the same distance as the outer tire. The result is "scrub", as in, the inner tire is actually being dragged/pushed by the outer tire. It's less noticeable the longer the wheelbase, but it's there, trust me, lol. Shorter wheelbase exaggerate the action, which is why the selectable lockers were designed. Think cj3/5/7, samurai wheelbases. [/QUOTE]
