Installation Notes and Tips

Verify the vehicle’s steering line routing and end connections before installation. This assembly uses a 3/8-inch ID hose end and a 3/8-inch male quick connect end, so matching the original configuration is important for proper sealing and fit. Confirm whether the application is gear-to-cooler routing, as shown in the fitment data for many Silverado, Sierra, Tahoe, Yukon, and Escalade models.

Inspect related steering components, clamps, and line mounting points for wear or corrosion before installing the replacement hose. The part number 3402322 should be matched to the vehicle’s exact year, make, model, and steering line layout.
