Abstract: The protective plate assembly may protect a wheel differential and drive line of a land vehicle from damage and from causing damage. A wheel differential plate may have two axle mount members extending upwardly therefrom and a plate mounting bracket may be attached at an upper end of the axle mount members that may be attachable to an axle housing. A drive line assembly may be attached to the wheel differential plate wherein the drive line assembly may have a bottom plate and two side walls extending upwardly therefrom. A rod may be attached to a front end of the drive line assembly wherein the rod may be positioned to slidably engage a rod mounting bracket that may have an aperture therein and the rod mounting bracket may be attachable to a land vehicle structure to retain the drive line assembly to partially enclose a drive line.
