Power Steering Debris

High-pressure steering units require excellent lubricants to function properly. Damage to gears, seals, O-rings, bearings and bushings, and poor spool valves are dramatically increased by poor quality lubricants. Critical brass and other soft alloys rely on the proper balance of lubricant additives to ensure long power steering life and trouble-free operation.

Service need:

The power steering pump produces high pressure between 800–2000 pounds, with high heat. This leads to fluid breakdown and failure. Symptoms include groaning and whining noises, erratic steering and pump leaks.

Solution:

A powerful cleaner suspends and dissolves varnish and gums in the power steering system and then all of the old fluid is flushed and replaced with new high-tech power steering fluid for both conventional sector and rack and pinion. The benefit will be a quieter-operating, longer lasting power-steering system.

Grooves are worn into the soft metal of the spool valve housing by hardened seals. Metallic debris from such wear accumulates in the fluid causing premature component failure!
