Product Details

The BBB Industries New Power Steering Pump line focuses on replacement steering components built for service on GM trucks and SUVs. This N731-2138 unit uses a reservoir-style inlet, a single threaded outlet, and a cast iron housing to match the needs of select Chevrolet and GMC platforms from the 1990-1995 model years. It is a direct-fit power steering pump for applications that call for an integrated reservoir and a press-on pulley setup.

This part cross-references OE-style numbers such as 19153678 and 19319787 for the same application. Use N731-2138 when replacing a worn power steering pump on Chevrolet C1500, GMC K1500, and related full-size truck and SUV platforms.

Common Problems This Part Can Address

• Hard steering effort at low speeds
• Whining or groaning from the power steering system
• Fluid leakage from a worn pump body or outlet connection
• Reduced steering assist after pump wear
• Reservoir-related service issues on older GM steering systems

Installation Notes and Tips

Verify reservoir-style fitment, outlet thread size, and mounting-hole layout before installation. This pump uses a press-on pulley attachment type and does not include a pulley, so the existing pulley must match the application or be transferred as required. For best results, inspect the steering hoses, reservoir condition, and fluid for contamination before installing the new pump.

Fitment notes in the catalog indicate that some Chevrolet and GMC applications recommend replacing the reservoir for optimal power steering pump performance, and certain 7200 lb GVW applications require reservoir-equipped configurations. Confirm the vehicle’s original steering setup before ordering.

Quality Assurance

BBB Industries supplies this New Power Steering Pump as a new replacement component for select Chevrolet and GMC applications. The cast iron housing, integrated reservoir, and application-specific outlet and mounting design support consistent service replacement on compatible GM trucks and SUVs.
