Detailed Description

Sunsong 3402430 is a power steering return line hose assembly designed for vehicles that need a direct replacement on the return side of the steering system. This hose assembly uses a 3/8 in. ID hose connection on one end and a 16 mm male O-ring fitting on the other, with a 35 in. length to match the routing requirements of the listed applications. It is built from CSM hose material and is rated for up to 250 psi, making it suitable for the lower-pressure side of the power steering circuit where heat and fluid exposure are common. This part number, 3402430, is listed for multiple Chrysler, Dodge, and Plymouth models, including Chrysler LeBaron and Dodge Spirit.

What This Part Helps Address

• Power steering fluid seepage from a worn return hose
• Cracked or hardened hose material from heat and age
• Incorrect hose routing or fitment after replacement
• Loss of steering assist caused by return-side leakage
• Corrosion-related deterioration in exposed steering hose components

Installation Notes and Tips

Verify the end fittings, hose length, and routing before installation. This assembly is listed for return-line use only and should be matched to the vehicle’s steering hose configuration. Confirm fitment against the vehicle’s year, make, and model, including applications such as 1990-1995 Chrysler LeBaron, 1990-1995 Dodge Spirit, and 1989-1995 Plymouth Acclaim. The part number 3402430 should be checked against the removed hose and connection style before final installation.

Quality Assurance

Sunsong states that its return hoses are engineered to exceed original equipment performance standards for return-side steering service. The tubing is manufactured from high-grade steel with zinc electroplating for corrosion and rust resistance against humidity, road salt, water, and grime, helping maintain durability in demanding underhood and road conditions.
