That, and the shifter sheet (it's kinda like an o-ring, but instead of sealing, it's holds your shifter in the right place) are the big thigns that go out. After 10+ years and many miles they just need servicing. If you ever plan on going into 4WD in your samurai, buy the $15 t-case shifter sheet. Takes about 30 min to swap out and will keep you from getting stuck in a gear range or neutral. While you're out and about.
