Detailed Product Overview

This power steering pressure line hose assembly is designed to restore hydraulic steering flow between the pump and steering gear on compatible Jeep platforms. Sunsong 3401653 uses high-grade steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime, while the CSM hose section supports long-term pressure performance. The 16 mm and 18 mm male O-ring ends help maintain a secure seal, and the integrated PS switch port supports the original system layout on the listed vehicles. This part cross-references Gates 355990 and Dayco 71242 for the same application.

Common Steering Issues This Hose Can Address

• Power steering fluid leaks from a worn or corroded pressure line
• Hard steering caused by pressure loss in the hydraulic circuit
• Noise from a restricted or damaged steering hose
• Rust-related hose deterioration in high-humidity or road-salt environments
• Fitment problems when replacing an aging OE-style pressure hose

Installation Notes and Tips

Verify the end fitting sizes, hose length, and PS switch port configuration before installation. Inspect mating seals, routing points, and nearby components for wear or contamination, and confirm the hose follows the original path without kinks or contact with hot or moving parts. Because this assembly is precision engineered for the listed Jeep applications, correct routing and clean connection surfaces are important for leak-free operation.

Each Sunsong pressure hose is pressure tested before it leaves the factory to help ensure proper operation after installation. The hose assembly is built to exceed original equipment performance standards for pressure, burst strength, and tensile load, supporting dependable service on Jeep Cherokee, Jeep Comanche, and Jeep Wagoneer steering systems.
