Installation Notes

Proper front strut mounting hardware installation is essential for safe suspension operation and dependable handling.
Before installation, inspect the strut mounting assembly, threaded fastener, mounting surfaces, and surrounding suspension components for damage or corrosion.
Confirm that the replacement nut matches the original hardware and is compatible with your specific vehicle and suspension configuration.
Position the strut assembly correctly before installing the replacement nut.
Carefully start the new Honda OEM flange nut by hand to prevent cross-threading.
Always follow the factory service manual for the correct installation procedure and torque specifications for your specific vehicle.
Use a calibrated torque wrench and avoid overtightening, as excessive force can damage the mounting threads or surrounding components.
When installing aftermarket coilovers, confirm that the original Honda mounting nut is compatible with the coilover manufacturer's hardware requirements.
Important: If your strut assembly requires removal of the center shaft retaining nut, follow the manufacturer's instructions for safely handling the spring-loaded strut assembly. Never loosen spring-retaining hardware without properly controlling the spring's stored energy.
After installation, verify that all suspension components are properly positioned and securely fastened.
A professional wheel alignment is recommended after suspension repairs that affect wheel alignment.
