Apparatus and methods for eliminating back drive in a push pull type control system, are provided. An exemplary apparatus includes a control rod (31)including a pair of spaced apart piston displacement members (67,69) each configured to carry a check valve (83,87). The apparatus also includes a pair of opposite-face check valves (83,87) each configured to seal against respective opposing face of a piston head (45) to form a hydraulic lock, preventing back drive in the control system.
