Newbie Question

Just took my new M817 (it's bobbed) in the snow for the first time and noticed I'm definitely not in 4 wheel drive. Am I missing something? I thought they were full time 4 wheel drive. Does the front axle manually engaged?
Thanks

yes when rear wheel slip front should engauge

You have the sprague gear front axle. If the rear tires slip the fronts will engage, if its working properly.

What are the likely problems?

Have you downloaded and started to read the free Tm's. Do you hear air when you shift from forward to reverse ? you could jack it up on jackstands and see what turns by hand first.

I have read a lot but couldnt find issue and yes I hear the air when I shift.
Appreciate the help

The rear wheels have to be turning faster than the front to engage. Jack it up and spin the wheels in the front to see if it turns the prop shaft or vice a versa.That way you know the axle/prop shaft work ok
