The hose is also pressure tested before it leaves the factory to support reliable installation and operation.
What This Hose Helps Fix
- Power steering fluid leaks at the pressure line
- Loss of steering assist from a damaged hose
- Noise caused by pressure-side hose wear or seepage
- Corrosion-related failure in steel tubing
