In a sidekick, there's a little rubber plug on the side of the t-case and during installation, there will be 1 ball that goes in there that rides in between the 2 shifting shafts. That's where i forgot to put mine, but worked it out before I finished bolting it all up. The samurai may be the same, or may not. You have to remove the clutch and shaft, then install the ball in thru that hole, reinstall the shaft, and set in the other ball and spring.
