There are, but not physically engaged. Which is why I simply leave it in auto if it's raining and what not. I don't need 4wd all the time but with road conditions, pot holes, standing water, etc I'd like it to kick in if needed during bad weather. Also when somewhere like the beach were you don't want to stall in the sand either but you make sharp turns and don't want to be in 4wd all the time.
It's one of those settings that has very little uses more of a convince factor.
Yes. But spinning the parts when not needed burns more fuel, and puts wear and tare on parts that don't need it. Also... since our BW44-44 T-case is new... we don't know exactly how long the electronic clutch pack will last if you simply leave 4wd auto engaged. It will shift in and out on every little slip of the rear. Also... the other unknown, is how long it holds 4wd once the computer feels a slip. If it locks up when the roads are dry... then if you go a round a corner... that will put A LOT of pressure on the electronic clutch. (may cause it to slip and wear) If you are truly in a slick condition... then the stress on the clutch is low, since a tire will slip instead.Spinning but not engaged. If it were engaged it would be 4wd
