Key Four Wheel Drive.

No it's not broken; Mal Story's conversion has real four wheel steering. The rear wheels can be steered independently of the front ones by hydraulic power but only in low ratio - otherwise life would be just a bit too exciting on the freeway. The chassis is from a Range Rover but the bodywork is not Land Rover, it just looks Land Rover - why?!# The picture was taken at the 4WD Field Day
This rear detail shows the rear radius arm, coil spring and Poly-Air air bag inside the coil. If the front and rear wheels steer in the same direction the vehicle can crab side-ways - especially useful when you get that slipping feeling on a greasy hill side. If they steer in opposite directions the vehicle will turn on a sixpence - great for parking.

Key Four Wheel Drive also sell Maxi-Drive diff locks.
