Car has an announcement of a transfer case not engaging, not sure what that means. No codes in the system. Worst case scenario is that it will need a replacement. Would like to know the procedure for replacing it with a used one, in case i buy the car tomorrow. I hear sometimes it's the chain inside the case or even the motor as the case in BMW's x5.
