The Sunsong Power Steering Pressure Line Hose Assembly 3402568 carries pressurized fluid from the power-steering pump to the steering gear, and it drops in as a direct-fit replacement for the 2007-2010 Toyota Sienna — see the Buyer's Guide tab for the engine-level applications. Cracked, chafed, or leaking pressure lines are common reasons for a low reservoir, whining assist, or fluid seepage; if a failed line is the cause, this assembly replaces it.
- Pre-assembled with brackets: the pressure and return hoses come ready to bolt in, cutting labor time versus lines sold as individual pieces.
- Precision engineered to exact fit: includes the additional components needed so worn parts are restored to original condition.
- Built to exceed OE performance: the pressure hose is rated for a 1,500 psi max working pressure, an 8,700 psi burst pressure, and 1,600 lb tensile strength for durability and long life.
- Factory pressure-tested: every pressure hose is subjected to a high-pressure quality-assurance test before it leaves the factory.
