Help cushion the rear shock-to-knuckle connection with the KYB Knuckle Bushing SM5051, a direct-fit replacement for the listed applications. It fits many vehicles, among them the 1986-1997 Honda Accord, 1988 Honda Civic and 1997-1999 Acura CL; see the "Vehicles it fits" section for the full list. It sits at the rear shock location, cushioning the joint where the shock meets the knuckle.
Rubber isolation: The rubber bushing cushions road impacts and helps absorb the noise, vibration and harshness that would otherwise carry into the vehicle.
Quieter ride: A fresh, resilient bushing helps maintain a tight connection and helps damp the rattles that develop once the original rubber hardens and cracks.
Direct fit: Made to serve as a direct-fit replacement for the listed applications.
Over time the original rubber hardens, cracks and separates, letting the shock-to-knuckle connection move and produce clunks, knocks or vibration from the rear. If a worn knuckle bushing is the cause, replacing it with SM5051 replaces the worn part at the mounting point. Inspect the rubber for cracking or separation, and diagnose the source of any noise before replacing.
