The Sunsong 3403017 power steering return line hose assembly is built for low-pressure, high-temperature return-side service. It is engineered for direct replacement on select Jeep Cherokee, Jeep Comanche, and Jeep Wagoneer applications from 1987-1990.

• Power steering return line hose assembly for return-side fluid routing
• 3/8 in. ID hose end and 3/8 in. male O-ring end
• 34.5 in. overall length for application-specific routing
• Steel and rubber construction for strength and flexibility
• Max working pressure of 250 psi
• Zinc-coated steel tubing for corrosion and rust resistance
• Precision-engineered to exact fit for the listed Jeep applications

Application Details

Compatible with 1987-1990 Jeep Cherokee, 1987-1990 Jeep Comanche, and 1987-1990 Jeep Wagoneer, this return hose assembly is built to restore the steering system’s return-side fluid path. The Sunsong 3403017 is formed from high-grade steel with rubber hose sections and is designed for the lower-pressure side of the power steering system, where heat and fluid exposure are common. This part cross-references Dayco 80412 and Gates 363610 for the same application.

What It Helps Fix

• Power steering fluid seepage at the return line
• Cracked, hardened, or deteriorated hose material
• Corrosion on the original steel tubing
• Improper hose routing or fitment on replacement repairs
• Noise or steering performance issues caused by fluid loss

Installation Notes

Verify end fittings, routing, and length before installation. This assembly uses a 3/8 in. ID hose connection on one end and a 3/8 in. male O-ring fitting on the other, so matching the original connection style is important. The listed Jeep Cherokee, Jeep Comanche, and Jeep Wagoneer applications include an adjustable length option, so confirm vehicle-specific routing and bracket locations during service.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The zinc-coated steel tubing is specified to resist corrosion from humidity, road salt, water, and grime, helping maintain durability in demanding underhood and underbody conditions.
