Over time, the vibration insulators in a strut mount can harden and let noise and vibration pass into the vehicle. This KYB mount cushions the jolts from road bumps, which helps reduce that jarring effect. Its front bearing plate serves as a steering pivot and helps support vehicle weight, so it plays a key role in steering performance and wheel alignment.

Signs this suspension strut mount kit may need replacing include clunking or knocking over bumps, a popping or binding feel when turning the steering wheel, and more road noise or vibration than usual. Worn struts or other suspension parts can cause similar symptoms, so diagnose the cause before replacing.
