Product Details

This Cardone Power Steering Pump line is built from decades of reverse-engineering experience and is intended to deliver OE-style steering feel on the road. The 96-55859 uses an O-ring hose port, threaded outlet, hose barb inlet attachment, and a 16x1.5 outlet thread size. It is supplied with a hydraulic pump, instruction sheet, and sealing kit.

This part cross-references Buick 26050488 and 26086103 for the same application. It is a direct-fit choice for drivers searching for a power steering pump for 1997-2004 Buick Regal, 2000-2003 Chevrolet Impala, or 1997-2003 Pontiac Grand Prix.

What It Can Help Fix

  • Whining or groaning from the power steering pump
  • Hard steering at idle or low engine speed
  • Uneven steering assist after pump replacement
  • Noise and vibration caused by shaft or bushing wear
  • Fluid leakage related to worn seals or contaminated hydraulic components

Installation Notes

Before installation, flush the steering system and use the OE-specified fluid. Cardone notes that an optional in-line filter must be installed for warranty coverage on listed applications, and the system should be cleaned with the supplied seal kit during service. If the original pulley has a loose fit after removal, replace the pulley rather than reusing a damaged one.

For vehicles such as the Buick Regal, Chevrolet Impala, Chevrolet Monte Carlo, and Pontiac Grand Prix, inspect the steering gear, hoses, and flow control valve for contamination or binding before installing the new pump. If assist only appears at higher engine rpm, check for air in the system, restricted flow, or steering component issues.

Quality Assurance

Cardone designs this new power steering pump to fit and perform like the original equipment unit. Each pump is computer load tested and built with premium seals to support reliable operation under demanding driving conditions.
