Claim:
An amphibious vehicle having a prime mover, seating arrangements, at least two road wheels and a hull defining a water-line, wherein two road wheels are each arranged to be driven from the prime mover at least by means of a primary shaft and an intermediate shaft between each wheel and each primary shaft, each intermediate shaft having an articulatable torque transmitting joint at each end so as to enable each driven wheel of the road wheels to be moved upwards from a lowered, ground engaging position to a raised position above the vehicle's water-line, wherein each said driven wheel is mounted rotatably to an intermediate suspension member, the intermediate suspension member being mounted to and between an upper suspension member and a lower suspension member, the lower suspension member being accommodated within a narrow recess in the hull of the vehicle when its driven wheel is in the raised position, characterised in that the intermediate shaft is encaged by a cage means mounted between the intermediate suspension member and the hull of the vehicle so as to resist torsional forces on the intermediate suspension member when the wheels are rotating or being braked.
