Detailed Description

Sunsong 3405248 is a power steering pressure line hose assembly for Land Rover Discovery steering systems. It is built to meet demanding pressure requirements, with steel tubing protected by zinc plating to resist rust and corrosion from humidity, road salt, water, and grime. The hose is precision engineered for the listed Discovery applications and is intended to restore proper steering fluid transfer in vehicles that need a direct replacement pressure line. This part cross-references Edelmann 92674 and Gates 366107 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure loss in the hose assembly
• Corrosion-related deterioration on exposed steel tubing
• Fitment issues from an incorrect replacement hose on a Land Rover Discovery
• Steering noise or inconsistent steering feel related to hose failure

Installation Notes and Tips

Verify the end fittings, hose routing, and vehicle configuration before installation. This part uses a 16 mm male O-ring on one end and a 7.8 mm flange on the other, so matching the original connection points is important for proper sealing and alignment. Inspect surrounding steering components, clamps, and mounting points for wear before installing the new hose on your Land Rover Discovery.

Quality Assurance

Each hose is pressure tested before it leaves the factory to help ensure reliable installation and operation. Sunsong builds this pressure line to exceed original equipment performance standards for strength, pressure capacity, and corrosion resistance.
