Product Details
Cardone Power Steering Pump 20-8705 is remanufactured to meet or exceed original equipment performance targets. The pump is inspected for design improvements where applicable, then rebuilt with attention to the hydraulic components that affect steering feel, noise, and long-term reliability. This part cross-references Buick/Chevrolet/Oldsmobile/Pontiac OE application 7839792 for the same application.
For drivers searching for a remanufactured power steering pump for 1980s full-size GM cars, this unit supports direct replacement needs on Chevrolet Caprice and Impala, Oldsmobile 98 and Delta 88, and Pontiac Bonneville, Catalina, Laurentian, and Parisienne models. The 20-8705 part number is also a useful reference when sourcing a replacement pump for Buick LeSabre applications.
Common Problems This Pump Can Address
- Whining or noisy power steering pump operation
- Low or inconsistent steering assist
- Hard steering after pump failure or internal wear
- Fluid leakage from worn seals or aging hydraulic components
- Pressure loss caused by valve or flow-control wear
Installation Notes and Tips
- Flush the system before installation to remove contamination and old fluid.
- Use the OE-specified power steering fluid for warranty-related service requirements.
- Inspect the pulley, hoses, and steering linkage before installing the replacement pump.
- If the system whines after installation, bleed trapped air from the hydraulic circuit.
- Some systems require a vacuum pump to fully remove air during bleeding.
- Check the flow control valve area and high-pressure fitting for debris if steering assist is uneven.
