Detailed Product Information

Sunsong 3405234 is a power steering return hose assembly developed for vehicles that route steering fluid from the gear to the cooler. The assembly uses CSM construction and OE-style connection points to support a precise replacement on Mercedes-Benz Sprinter and Dodge Sprinter platforms. This part cross-references Monroe Shocks & Struts (e.g., 5801) for the same application.

As a direct-fit style replacement, this hose assembly is suited for owners and technicians servicing the power steering return circuit on Sprinter vans. The part number 3405234 is also referenced in aftermarket catalogs for the same application, making it easier to match the correct hose during repair work on Mercedes-Benz Sprinter and Dodge Sprinter models.

Common Problems This Part Can Address

• Leaking power steering return hose connections
• Cracked or hardened hose material from age and heat exposure
• Incorrect routing or fitment on gear-to-cooler steering lines
• Fluid seepage at the flange or hose-end connection
• Restoring proper steering fluid return flow after hose failure

Installation Notes and Tips

Verify the vehicle year, make, model, and steering line routing before installation. This assembly is specified for gear-to-cooler applications, so confirm the existing hose follows the same path and uses the same flange and ID hose end styles. Inspect adjacent fittings, brackets, and cooler connections for wear or corrosion before installing the new hose. The included bracket supports OE-style placement, but final alignment should match the original routing on the vehicle.
