What It Helps Address

• Excessive steering play or looseness in the steering wheel
• Uneven or delayed steering response
• Fluid leakage at the steering gear housing or ports
• Binding, rough steering effort, or inconsistent assist feel
• Wear-related steering gear failure on GM truck and SUV platforms

Installation Notes

Verify the input shaft type, port thread sizes, mounting hole count, and pump rotation before installation. Confirm vehicle-specific options such as wheel size, package code, hybrid status, off-road package, or production code, since the listed Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and related applications include configuration-specific fitment. After installation, bleed the power steering system and inspect all O-ring connections for leaks.

Quality Assurance

This remanufactured steering gear box is built by Maval for OE-style replacement use in the listed GM applications. The remanufactured format supports replacement of a worn steering gearbox while maintaining the specified shaft, port, and mounting dimensions required for proper fitment.
