Detailed Description

BBB Industries N103-0273 is a hydraulic rack and pinion assembly engineered for the steering gear application on the Hummer H3. This part number, N103-0273, matches 2006-2008 Hummer H3 models with power steering and 14mm diameter tie rods, making it a focused replacement for steering systems that need a new rack assembly rather than a remanufactured unit. The rack length measures 47.625 inches, and the assembly uses a 0.75 inch input shaft diameter with a 1.875 inch input shaft length for proper steering column connection.

The BBB Industries New Rack and Pinion line is positioned as a new replacement product line for steering repair, and this assembly includes inner tie rods and bushings to support a complete steering gear service. Part number N103-0273 also cross-references 19320562 for the same application.

What This Part Helps Address

• Steering play or looseness in the Hummer H3 steering system
• Fluid leakage from worn hydraulic rack seals or ports
• Uneven steering response caused by internal rack wear
• Noisy or inconsistent steering effort during turning
• Wear at the steering gear assembly that affects road feel and control

Installation Notes and Tips

Verify the vehicle is a 2006-2008 Hummer H3 with power steering and 14mm diameter tie rods before installation. Confirm hydraulic port thread sizes, mounting hole spacing, and input shaft dimensions against the original steering gear. Because outer tie rods are not included, reuse or replace them as needed during the repair. After installation, perform a full alignment and inspect the hydraulic system for leaks and proper steering operation.

Quality Assurance

BBB Industries supplies this as a new steering component, not a remanufactured unit. The part is built to match the listed fitment and dimensional specifications for the Hummer H3 application.
