Detailed Description

Sunsong 3404995 is a power steering pressure line hose assembly for the BMW M3, covering 2008-2013 models routed to the rack. It is built to meet demanding hydraulic requirements with a 1,500 psi maximum working pressure, 8,700 psi burst rating, and 1,600 lb tensile strength. The hose assembly uses high-grade steel tubing with zinc plating to help resist rust and corrosion from humidity, road salt, water, and grime.

This part number 3404995 is precision engineered for exact fitment and includes the bracket needed for the application. It is a practical replacement for a BMW M3 power steering pressure hose when the original line is leaking, damaged, or no longer holding pressure. This part cross-references Monroe Shocks & Struts (e.g., 5560) for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked or worn pressure line
• Loss of steering assist caused by pressure loss in the hydraulic circuit
• Noise or stiffness in steering linked to a failing hose assembly
• Corrosion damage on the original BMW M3 pressure line
• Fitment issues when replacing a bent or deteriorated steering hose

Installation Notes and Tips

Confirm routing, fitting style, and connection sizes before installation. This assembly uses a banjo fitting on one end and a female fitting on the other, so the existing hard lines and rack connection should be inspected for wear, thread damage, or contamination. Replace any degraded sealing surfaces during service and verify that the hose is routed away from heat and moving components.

For BMW M3 applications, bleed the power steering system after installation and check for leaks with the engine running and the steering turned lock to lock. Part number 3404995 is intended for the listed to-rack configuration only.

Quality Assurance

Each Sunsong hose is pressure tested before it leaves the factory to help ensure proper operation and straightforward installation. The construction is specified to exceed original equipment performance standards for pressure capacity and durability.
