Running with power divider on

Wow, so many threads on power dividers and some people still don't understand how they work? All it is a an differential between rears. Each rear has a differential to allow power to BOTH wheel ends while they are rotating at different speeds (like when you turn). The power divider does the same thing between rears, allowing the rears to turn at different speeds while still powering both (like if 1 axle has more tire wear than the other). BOTH drive axles are ALWAYS powered when you have traction.

The downfall of any differential is what happens when you lose traction. If it is easier for any wheel to spin rather than move the truck, the power will take that path of least resistance. So all it takes is 1 of the 4 wheel ends to lose traction to get stuck. When you lock the power divider in, it eliminates the inter-axle differential, forcing both axle differentials to turn at the same speed. Now you need 2 wheel ends (1 on each axle) to lose traction to be stuck.
