  • Precision-surfaced shafts to reduce premature seal wear
  • Supplied with calibrated pressure relief valves
  • Earth-friendly remanufacturing process reduces raw material and energy use versus new part production

Product Details

Cardone’s Power Steering Pump line focuses on remanufactured OE components that are inspected, upgraded where needed, and tested before release. Part number 21-5915 uses an aluminum housing, threaded outlet, hose barb inlet attachment, and press-on pulley design. It is supplied without a reservoir and is intended for remote reservoir systems. This part cross-references Audi 048145155F for the same application.

Common Steering Problems It Can Address

  • Hard steering or reduced assist
  • Whining or pump noise during operation
  • Fluid leakage from worn seals or shaft surfaces
  • Inconsistent steering effort after pump failure
  • Poor hydraulic pressure or bypass performance

Installation Notes and Tips

  • Fits 1992-1994 Audi 100, N/A
  • Fits 1992-1994 Audi 100 Quattro, N/A
  • Fits 1995-1997 Audi A6, N/A
  • Fits 1995-1998 Audi A6 Quattro, N/A
  • Reservoir not included; reuse or source the correct remote reservoir setup as needed
  • Flush the system and install an in-line filter to help prevent contamination-related repeat failure
  • Use OE fluid and follow the vehicle manufacturer’s fluid change interval recommendations
  • Inspect the pulley before installation; a loose-fit pulley or damaged shaft can require pulley replacement

Quality Assurance
