What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Steering effort caused by pressure loss in the hydraulic line
• Noise or inconsistent steering assist related to hose deterioration
• Corrosion-related failure in exposed steel tubing
• Fitment issues from an incorrect replacement hose on Audi A4, Audi A6, Audi Allroad Quattro, or Volkswagen Passat applications

Installation Notes and Tips

Verify end fitting sizes and routing before installation: 16 mm female bubble flare on one end and 14 mm banjo on the other. Confirm whether the vehicle uses a rack or gear connection, since fitment varies by model year and chassis. This hose does not list a bracket or power steering switch port, so compare the original line to the replacement before installation. For best results, inspect related seals and steering components for wear before refilling and bleeding the system.

Quality Assurance

Sunsong pressure hoses are manufactured to exceed original equipment performance standards, with each hose subjected to high-pressure testing before shipment. The steel tubing is zinc electroplated to improve resistance to rust, road salt, water, humidity, and grime. Part number 3402058 is built for consistent installation and dependable steering system operation.
