Description

When internal steering gear components wear out, your vehicle's steering may feel vague and floaty, leading to lane drifting and imprecise cornering. The USA Standard Gear ZSG7512 is a power steering gear box designed to restore steering response and control. Key specifications for this steering gear box include a black powder-coated finish, a 0.725-inch input shaft diameter with 25 splines, and a 1.25-inch output shaft diameter with 32 splines. It is power assisted and features a total of 3.34 turns lock-to-lock. The pressure port thread size is 11/16-18, and the return port thread size is 5/8 X 18, with four mounting holes for secure attachment. USA Standard Gear recommends replacing the Power Steering Pressure and Return Hoses when replacing the steering gear, as old hoses can degrade internally and contaminate the new unit. It is also critical to completely flush the power steering system with an OE-approved Power Steering Fluid prior to installation to prevent contamination and failure. Consider installing a Power Steering Filter on the return hose to further extend the life of the steering components. Finally, ensure the system is properly bled to prevent noise and ensure optimal performance. This power steering gear box is specifically designed for select 1975-1984 Chevrolet, GMC, and 1978-79 Dodge truck and SUV applications, including 2WD models. It is a direct fit replacement that helps resolve vague steering and imprecise cornering caused by worn components.
