The BD UnLoc transfer case control allows the operator to manually disable the front wheel drive mechanism while the transfer case is in 4WD low range, holding the front hubs in free mode so the front wheels are not driven. This restores two-wheel maneuverability in low range, permits sharp full turns without front axle u-joint hopping or binding, and routes full torque to the rear wheels only while in low gear range.
