Product Details

This AAE New Hydraulic Power Steering Pump is part of the Atlantic Automotive Enterprises New Power Steering Pump line, built for direct replacement service on GM steering systems that require a reservoir-equipped pump. The design focuses on OE-style operation and fitment for vehicles such as the 2004-2006 Chevrolet Silverado 1500, 2001-2003 Chevrolet Silverado 1500, and 1997-1999 GMC K1500 Suburban. Part number 63238N is also cross-referenced with 15076608 and 88963509 for the same application.

Compatible With 1997-2007 Chevrolet Silverado, Tahoe, Suburban, Avalanche, C/K and 1997-2007 GMC Sierra, Yukon, and Yukon XL applications listed in the fitment data, this pump is a direct service part for hydraulic steering repair. Use OE-approved power steering fluid and flush the system during replacement to protect pump life and maintain proper steering performance.

Common Steering Problems This Part Addresses

• Hard or inconsistent steering effort.
• Noise from a worn or failing hydraulic pump.
• Loss of steering assist from internal pump wear.
• Fluid flow issues caused by a restricted reservoir.
• Fitment issues when replacing an OE-style reservoir pump assembly.

Installation Notes

Before installation, flush the steering system and refill it with OE-approved power steering fluid. Inspect the steering fluid reservoir and replace it if contamination or clogging is present, since a restricted reservoir can starve the new pump. Confirm pulley and vehicle configuration details against the fitment notes, including applications listed without a pulley and with reservoir and cap.
