Yesterday I was driving my Samurai very gently on the streets (no off-roading), and just as I was driving I heard a click in the transfer case, and all the sudden power stopped being transferred to the rear wheels. The shaft between the gear box and the TC is turning, but the TC is not transferring anything to the wheels. I tried to move the TC stick, but it seemed to be jammed. I have recently upgraded the TC to Tough Gear 6.5:1 gears, and I used it while off-roading a couple of weeks ago without any problems, but suddenly this happens while driving on a street. What could be the problem? I took the car to a workshop to inspect the TC, but I'm very disappointed, I certainly don't want to go back to stock TC, after experiencing the might of 6.5:1.
