A method of protecting a multi-function drive axle system from damage, comprising the steps of: determining the axle torque and speed from sensors positioned on the multi-function drive axle system; using the axle torque and speed to approximate damage values for the driveline of the multi-function drive axle system; comparing the approximated values of driveline damage with driveline damage durability targets; identifying if the approximated values of driveline damage exceed the driveline damage durability targets; and limiting the engine torque and/or speed to produce an axle torque and speed corresponding to driveline damage values that do not exceed the driveline damage durability targets.
