Keep the steering assist firm and quiet with the Sunsong Power Steering Pressure Line Hose Assembly (MPN 3401189). It installs as a direct-fit replacement for the 2001-2003 Toyota Highlander, routing pressurized hydraulic fluid from the power steering pump to the steering gear so the system can build the assist you feel at the wheel.
This assembly arrives as a complete hose-and-fitting unit, ready to replace an original line that has begun to leak, seep, or restrict flow.
Signs the original line may need replacing include power steering fluid leaks near the hose or fittings, a low reservoir, a whine from the pump, or steering that feels heavier than normal. If a failed pressure line is the cause of those symptoms, this assembly replaces it; diagnose the source of a leak before installing.
