This part cross-references Gates 71061 and Four Seasons 623 for the same application.

What This Part Helps Address

• Power steering fluid leaks from a worn pressure hose
• Steering assist loss caused by hose cracking or internal wear
• Noise or erratic steering response related to pressure-line failure
• Corrosion-related deterioration on exposed steel tubing
• Fitment issues when replacing an aging OE-style hose assembly

Installation Notes and Tips

Verify the vehicle uses the listed rack-and-pinion configuration before ordering. Confirm both end fittings match the system connection points: 9/16 in. swivel O-ring on one end and 5/8 in. swivel O-ring on the other. Check hose routing, clearance, and overall length against the original line before installation. Clean mating surfaces and inspect related steering components for wear or contamination during service.

Quality Assurance

Each hose is pressure tested before it leaves the factory to help ensure proper operation after installation. Sunsong also builds the assembly with corrosion-resistant tubing and high-pressure construction to support long-term steering system service.
