Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Steering effort that increases when hydraulic pressure is lost
• Cracked, corroded, or fatigued hose tubing
• Noise or inconsistent steering assist caused by pressure line failure
• Restoration of proper fluid transfer in Nissan 280ZX steering systems

Installation Notes and Tips

Verify the end fittings, hose length, and routing before installation on your Nissan 280ZX. Inspect mating components, seals, and hard lines for wear or corrosion so the new pressure line can seat correctly and maintain system integrity. After installation, bleed the power steering system and check for leaks under operating pressure.

Quality Assurance

Each Sunsong pressure hose is pressure tested before it leaves the factory to confirm proper operation. The hose assembly is also built with corrosion-resistant steel tubing and durable hose materials to support long service life in power steering applications.
