Controlled Traction Differential Control

SD DM 05.05.05

A controlled traction differential feature is included or available as an option on some rear axles. A control valve switch engages and disengages the controlled traction feature to cause the axle shafts to rotate together. See Fig.. The controlled traction, or differential lock, should only be engaged when the vehicle is moving slowly at low throttle to avoid causing internal axle damage. The differential lock must only be used for adverse road conditions. The use of the lock increases the turning radius and affects the vehicle handling. A guard is positioned around the switch to minimize accidental activation.
