Common Problems This Part Can Address
- Power steering fluid leaks from a cracked or worn pressure hose
- Loss of steering assist caused by pressure line failure
- Noise or stiffness in the steering system related to fluid loss
- Corrosion damage on the original steel tubing
- Poor sealing at the hose ends due to aged O-ring connections
Installation Notes and Tips
Verify the end fitting sizes before installation: 14 mm male O-ring on one end and 16 mm male O-ring on the other. Confirm hose routing matches the original layout on the vehicle and inspect adjacent steering components for wear, contamination, or fluid residue before completing the repair. This hose assembly does not include a bracket or PS switch port.
Quality Assurance
Each hose is pressure-tested before it leaves the factory to help ensure proper operation after installation. Sunsong states that this pressure hose line is built to exceed original equipment performance standards, with corrosion-resistant zinc-plated steel tubing for added durability in harsh road and weather conditions.
