Detailed Description

Sunsong 3403581 is a power steering pressure line hose assembly made for Jeep steering systems that require a precise replacement hose with the correct O-ring connections. This hose is specified for 1980-1987 Jeep J10, 1984-1986 Jeep Grand Wagoneer, 1980-1983 Jeep Cherokee, and 1980-1983 Jeep Wagoneer models, making it a focused solution for classic Jeep steering service. The 16 mm and 18 mm male O-ring ends help maintain the proper connection style for the pressure side of the system, while the 27.5-inch length supports the original routing layout.

The Sunsong 3403581 is manufactured to exceed original equipment performance standards, with a maximum working pressure of 1,500 psi, burst pressure rated at 8,700 psi, and tensile strength of 1,600 lb. High-grade steel tubing with zinc electroplating adds corrosion resistance against humidity, road salt, water, and grime. This part cross-references Gates 357020 for the same application.

Common Problems This Hose Can Address

• Power steering fluid leaks from a cracked or worn pressure line
• Loss of steering assist caused by hose failure
• Noise or stiffness from restricted fluid flow in the pressure circuit
• Corrosion-related deterioration on older Jeep steering lines
• Incorrect hose fitment after prior repair work

Installation Notes and Tips

Verify the fitting sizes and hose routing before installation on your Jeep J10, Grand Wagoneer, Cherokee, or Wagoneer. Inspect mating surfaces, seals, and nearby steering components for wear before connecting the new pressure line. Confirm that the hose follows the original path without twist or contact with hot or moving parts.

Quality Assurance

Each Sunsong hose is pressure tested before it leaves the factory to help ensure proper operation after installation. The hose assembly is engineered for exact fit and built with corrosion-resistant tubing to support long-term service in demanding steering applications.
