Lubegard Power Steering 2-Step System is the perfect solution for noisy or stiff power steering systems. It is used by professional technicians worldwide. It is fast and simple, with immediate results. Power steering systems are generally only noticed when something has gone wrong. This system is one of the simplest to maintain and is also the most noticeable when something goes wrong. A power steering system is generally subject to harsh temperatures leading to fluid deterioration over time. Through constant use and high operating pressures, other types of wear materials are also generated that degrade the system. The result of this pressure and heat is fluid breakdown, contamination, loss of lubricating properties and varnish deposits. When power steering fluid circulates throughout the system of pump and gear, it picks up wear material as well as contamination from the breakdown of aging hoses and seals. The periodic maintenance of this intricate and precise system is necessary. Flushing this system with Lubegard power steering flush and recharging it with new power steering fluid is the best assurance for extended optimum power steering performance, reduced noise and effortless steering. Even though most manufacturers don't provide a maintenance schedule for power steering service, it should be flushed and refilled any time work is done on the rack, a hose is replaced, or if there are steering squawk or other operating problems.
