Abstract
A lockout mechanism for a self-steering axle suspension system is provided by using the internal fluid reservoir and piston of a shock absorber normally used to dampen oscillations of the wheels in such a suspension, by employing a selectively actuatable valve in the fluid flow path provided by an orifice in the piston of the shock absorber to prevent or modulate the flow of fluid across the piston thereby to lock out the steerability of the system to the extent desired.
