I was trying to drive my 98 CRV EX up a steep snow-covered hill over the weekend when my wheels started spinning and I got stuck. I got out, dug out the snow from my front wheels, and tried moving forward again but much to my surprise my rear wheels, which were still on snow, started spinning. My question is, why was power directed to my rear wheels when it was my front wheels that had the traction? I thought the CRV's all time 4 wheel drive was supposed to send power to either the front or rear depending on which set had the better traction. Does anyone know how the CRV's 4x4 works? I'm thinking that once the front wheels started spinning the first time that the 4x4 automatically sent power to the rear wheels, and the power stayed with the rear wheels. How does the CRV know when to switch power from front to back and then to front again?
