transfer case problems
 

Need some input guys......Was hauling wood today and the transfer case started clunking. It happened whe you let off the throttle, or went from reverse to 1st gear. Made it about 10 miles, came to a stop sign, let out on the clutch and it gave way. Doesn't matter what position you put the transfer case lever...it won't move. Any iseas? Gonna tear into it tomorrow.
