Abstract
The invention relates to vehicle axles. Self-steering axle systems are known and are adequate when the vehicle is moving forward but not when the vehicle is reversed. The invention avoids this by having a stub axle assembly located on a support by a first pivot the support being mounted on an axle beam by a second pivot, a drive means to cause the support to pivot between two opertional conditions, and the two pivots being angularly disposed to provide a first castor angle in one position, second opposite castor angle in the second position.
