A method for controlling wheel hop at a vehicle axle includes determining that one of a difference between average front and rear wheel speeds exceeds a reference difference, a frequency of a signal produced by an accelerometer mounted on the axle exceeds a reference frequency, and a frequency of a lock ring torque exceeds a second reference frequency; pulsing pressure in the wheel brakes of the axle; and reducing engine torque.

A method for controlling a clutch of an electronic locking differential for a vehicle includes determining either that a speed of the vehicle is less than a reference speed or that a desired state of the clutch is a disengaged state, determining that an angular displacement of a steering wheel from a centered position is less than a first reference angle, and disengaging the clutch.
