Product Details

This BBB Industries power steering pump is built as a new replacement for vehicles that use a reservoir-style inlet and threaded outlet connection. The cast iron housing supports a robust pump assembly, while the included reservoir helps simplify service on applications where the reservoir is part of the pump setup. This part number N734-73133 is listed for 2003-2006 Chevrolet Trailblazer EXT, 2003-2006 GMC Envoy XL, 2003-2006 Isuzu Ascender, 2003-2005 Chevrolet SSR, and 2004 GMC Envoy XUV.

This part cross-references Monroe Shocks & Struts (e.g., 19320090, 26099941) for the same application.

What It Helps Address

• Hard steering effort caused by a worn or failing pump
• Noise from a pump with internal wear or pressure loss
• Fluid leakage at the pump or outlet connection
• Reduced steering assist during low-speed maneuvering
• Service replacement needs on Trailblazer EXT, Envoy XL, Ascender, SSR, and Envoy XUV applications

Installation Notes

Verify the reservoir-style inlet, M16x1.50 threaded outlet, and three-mount-hole configuration before installation. Replace worn steering hoses and inspect the fluid condition during service to help protect the replacement pump. Confirm pulley transfer requirements, since the pulley is not included and this unit uses a press-on pulley attachment type. For 2003-2006 Chevrolet Trailblazer EXT, 2003-2006 GMC Envoy XL, and 2003-2006 Isuzu Ascender applications, match the original pump layout before installation.

BBB Industries supplies this as a new power steering pump under its New Power Steering Pump line, with application-specific construction and included installation kit for service work. Part number N734-73133 is cataloged for direct replacement use on the listed GM and Isuzu vehicles.
