A device for maintaining axial self-adjustment of the pitman shaft in a manual steering gear assembly, the device including a flanged shaft extension secured to the end of the pitman shaft within the housing of the steering gear assembly, the shaft extension rotatably supporting a pair of cams which are fixed together to provide cam slots therebetween engaged by cam elements of a support cam non-rotatably fixed to the housing, the cams being rotatably biased in an up-ramp direction relative to the support cam by a spring to effect axial adjustment of the pitman shaft, a cam locking device being operatively connected to the cams to permit this axial adjustment to be accomplished only when the steering gear is essentially centered and to prevent axial adjustment during turning of the steering gear in either direction from the centered position.
