Common Problems This Pump Can Address
- Whining or noisy power steering pump operation
- Hard steering caused by low hydraulic pressure
- Uneven assist after pump wear or internal valve issues
- Fluid leaks from aged seals or O-rings
- Poor steering response after contamination in the hydraulic system
Installation Notes and Tips
Before installation, flush the system and inspect the reservoir, hoses, and steering gear for contamination. Cardone recommends using the suggested OE fluid and installing an in-line filter for warranty purposes on these Audi applications. If the system contains air after service, bleed it thoroughly; foam or bubbles in the reservoir indicate trapped air that must be removed. Verify pulley fit before installation, since press-on pulley applications require the correct pulley condition and shaft fit.
Quality Assurance
Every unit undergoes hydraulic efficiency testing to confirm reliable performance. Critical internal components are tested, seals are upgraded with HNBR material, and the final assembly is evaluated for pressure, flow, bypass, steering effort, and noise. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
