A vehicle axle includes first and second wheel hubs, first and second shafts, a hub lock, and a plug assembly. The first and second shafts extend into the first and second wheel hubs, respectively. The hub lock is configured to selectively couple the first shaft to the first wheel hub. The plug assembly is fixedly coupled to the second wheel hub and is fixedly coupled to the second shaft such that the second wheel hub, the second shaft, and the plug assembly rotate in unison.

Axle system for a vehicle

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.
