Power Steering Pump - 20-981

Metafield Product & Technical

The problem is most likely in the steering unit−the pump does not know left from right. Check for binding steering components and repair as necessary.


A whining pump is usually caused by air in the power steering system. Inspect the reservoir for proper fluid level. If fluid has foam or air bubbles present, air has entered the system or has not been properly bled (ensure all hoses/clamps are tight). Some systems require special vacuum bleeding procedures.


The pulley may have cracked upon removal. If the shaft was mushroomed before removing the pulley, it has now enlarged the bore in the pulley. The pulley must be replaced.


There may be debris in the flow control valve bore not allowing the flow control valve to move as it should. (Valve and bore are located behind the high pressure fitting on the pump). The system must be checked for contamination and flushed.


Yes. Some O.E. manufacturers recommend that power steering fluid be changed at 50,000 miles and continue at that interval. Just like engine oil, power steering fluid will eventually break down and carry suspended contaminants from component wear and breakdown. Follow your vehicle's O.E. manufacturer's recommendations on fluid change intervals.

Core

What is a core?

A core is a used automotive part that is returned to the remanufacturer instead of being scrapped.

Why return cores?

Cores are literally at the “core” of the remanufacturing process, because they are the raw material used to start the remanufacturing process. That’s why remanufacturers buy cores back from customers, and they pay the most for good quality cores. If a core has too much damage in key areas, it may be unusable or require extra resources to process; therefore a reduced core payment may be awarded. This core policy explains potential deductions that may be taken from the core price if certain components are missing or damaged.

What is remanufacturing?

Remanufacturing is the process of taking used parts, completely disassembling and thoroughly cleaning them, replacing the worn components with original quality components, and restoring them to their original function. Every unit is 100% tested to ensure O.E. performance.

Why “reman”?

PRODUCTS - Reman captures used, durable goods like auto parts and puts them “back on the road” to new and sometimes better than new performance. Reman provides the opportunity for detection of common failure modes and incorporation of design improvements to prevent repeat failure.

ECONOMY - Reman products cost consumers about 40% less than new. Reman products are one of the few “green” products that actually costs less than their “non-green” counterparts.


ENVIRONMENTAL - Reman saves up to 86% of the energy required to build a new unit. Reman realizes Greenhouse Gas savings of up to 25 lbs. per unit over new. Reman saves up to 85% of the raw material required to produce a new unit by reusing existing products. Reman is even more sustainable than recycling, as product castings are preserved rather than melted down to raw material, saving energy and reducing emissions.
