Detailed Description

Sunsong 3401688 is a power steering pressure line hose assembly for Jeep Cherokee and Jeep Comanche models with left-hand-drive configuration. It is built to meet or exceed original equipment performance standards, with a pressure rating up to 1,500 psi, burst pressure rated at 8,700 psi, and tensile strength of 1,600 lb. The steel tubing is zinc electroplated to help resist corrosion from humidity, road salt, water, and grime, while the precision-engineered layout supports proper routing and fit. Part number 3401688 is a direct-fit steering hose replacement for vehicles that require a male O-ring connection at both ends and a pressure switch port.

Common Repair Uses

• Restores steering assist when the original pressure hose is leaking
• Addresses fluid loss at worn hose fittings or line sections
• Replaces a corroded or damaged power steering pressure line
• Helps correct steering noise caused by pressure-side hose failure
• Supports repair of pressure switch port-related hose issues

Installation Notes and Tips

Confirm left-hand-drive fitment before ordering, since this hose is listed for LHD vehicles only. Verify the 16 mm and 18 mm male O-ring connections, hose routing, and pressure switch port location against the original line. Inspect related seals, clamps, and mounting points during service so the replacement hose seats correctly and the steering system can be bled after installation.

Quality Assurance

Each Sunsong pressure hose is pressure-tested before it leaves the factory to help ensure proper operation after installation. The hose assembly is manufactured with corrosion-resistant steel tubing and engineered to restore the original hose configuration for the listed Jeep applications.
