I just recently bought my 87' Cherokee, but I've wanted it for years...and I'm already in love with it. I'm having problem's getting my 4x4 to engage...I don't have an original manual can someone tell me the procedure...I've heard people say you have to roll backwards but that doesn't seem to work. There's nothing to lock in my front hubs...someone please help...a Jeep is not a Jeep without 4 wheel drive.:dunno:
