I recently purchased a 2017 RAM 1500 4x4. I believe it has the Bw44-45 transfer case because it does not have 4x4 Auto - only 4x4 lock and low. I'm not sure of the "dos" and donts of these settings other than that 4x4 low is for < 25mph speeds in very low traction conditions and/or when max torque is needed. I Really have no clue what "4x4 lock" is for. Mostly, I'm interested in learning what NOT to do so I don't damage the transmission. I am aware that it's never a good idea to just aimlessly use 4x4 when it's not needed e.g. cruise around dry roads with it on. But I still don't know what conditions I'd use 4x4 lock for. Can it be used for dirt roads or driving in wet/snow conditions at speeds up to 45-50mph?
Lastly, is it safe to turn in these modes? I've heard that differential health can be tricky in 4x4.
