Detailed Description
BBB Industries 503-0159 is a reman steering gear engineered for power steering systems on select 2001-2006 Cadillac Escalade, Chevrolet Avalanche 1500, Silverado 1500, Suburban 1500, Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL 1500 applications. It also fits Escalade ESV and Escalade EXT models in the listed years. The unit uses M18x1.50 inlet and M16x1.50 outlet connections, along with a 32-spline output shaft and 3.25 turns lock to lock for a direct-fit steering gear replacement.
This part cross-references ACDelco 19321404 and 26104949 for the same application. BBB Industries 503-0159 is a practical choice when replacing a worn steering gear on a Chevrolet Silverado 1500 or GMC Sierra 1500, especially where original steering feel, port sizing, and mounting configuration must match the vehicle.
What It Helps Fix
- Excessive steering play or loose steering feel
- Fluid leakage at the steering gear housing or ports
- Hard steering effort caused by internal wear
- Uneven or inconsistent steering response
- Noisy steering operation related to a worn gear assembly
Installation Notes and Tips
Verify the vehicle’s steering system configuration before ordering, including power steering setup, mounting-hole count, and port thread sizes. Confirm the application notes for trim/package-specific coverage on Silverado 1500 and Sierra 1500 models, since some years require exact option matching. After installation, inspect the hydraulic connections, bleed the system thoroughly, and perform a front-end alignment if steering components were replaced.
Quality Assurance
As a remanufactured BBB Industries steering gear, this unit is rebuilt for service replacement use and supplied with an installation kit. Confirm all fitment details against the vehicle before installation to ensure the correct match for the listed Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon applications.
