The following information may duplicate information already stated by other people. I'm just trying to add more information without having the time to read all the previous messages in total.

In standard four wheel open (normal driving mode) there is 40 percent torque to the front/60 percent torque to the rear.
You can lock the transfer case in HI or LO, and this gives you 50/50 front/rear.
The transfer cases are Borg Warner (BW) models 4493 (standard), or 4494 (off-road).
The front axle has a central disconnect feature. The axle uses a conventional ring and pinion gear set in order to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier.
The drive axles are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.


The electronic locking rear axle is controlled by the Traction control system. The actual mechanical locking rear axle (fully locking electronic rear differential), available with the off-road suspension package, mechanically locks the rear axles together via a solenoid. However, above 20 mph, the controller will unlock the axles for safety reasons.
Both axles are open differential designs.
