Detailed Description

Sunsong 3402566 is a power steering pressure line hose assembly made for 2007-2009 Chrysler Aspen and 2004-2009 Dodge Durango vehicles. It is built to restore steering fluid transfer between the pump and steering gear with the correct fitting sizes, hose length, and OE-style routing characteristics. This part number, 3402566, is a practical replacement when the original pressure hose shows leakage, cracking, corrosion, or pressure loss.

The hose assembly uses CSM hose material and steel tubing with zinc coating to resist corrosion from humidity, road salt, water, and grime. Sunsong also rates this hose above original equipment performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure, and 1,600 lb tensile strength. This part cross-references Dayco 80670 and Gates 352245 for the same application.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Hard or inconsistent steering assist
• Noise caused by low steering fluid pressure
• Corrosion-related hose failure on exposed steering lines
• Cracked or worn original hose assemblies

Installation Notes and Tips

Compatible With 2007-2009 Chrysler Aspen and 2004-2009 Dodge Durango, this hose uses 16 mm and 18 mm male O-ring ends and a 30 in. length. Confirm routing, fitting style, and connection points before installation. Replace worn seals and inspect nearby steering components for contamination or damage when servicing the pressure line. The part number 3402566 should be matched to the vehicle application before installation.

Quality Assurance

Each Sunsong pressure hose is high-pressure tested at the factory before it leaves production. That final inspection helps verify sealing and pressure integrity for trouble-free installation and operation.
