The present invention relates to a compact and light weight integral hydraulic power assisted steering gear arrangement comprising housing; a cylinder in the housing having pressure chambers; an axially bored rack piston slidably carried in the cylinder; an output shaft journaled on the housing for rotating about an axis with a sector gear; a worm extending in axial alignment into the bore of rack piston; an operating steering shaft journaled for rotation on the housing; a control valve positioned in valve chamber of the housing; and one or more covers fixed on to the housing through one or more locker wires for sealing the hydraulic fluid, supporting worm and output shaft. The rack piston is two separate components. The rack with axially bored helical grooves and a series of rack teeth is supported by rack supporter assembly on one side and by the piston on the other end.
