Quiet a harsh, noisy front strut with the KYB strut mount kit SM5425, a direct-fit replacement for the 2003-2006 Ford Expedition, 2004-2008 Ford F-150, and 2003-2005 Lincoln Navigator. This suspension strut mount kit connects the top of the front strut to the body, isolating road impacts while letting the strut pivot for steering — replacing old, hardened insulators that transmit noise and vibration into the cabin.
KYB builds this as an OE-quality replacement designed for each application. If clunking over bumps, added vibration, or vague steering trace back to failed front strut mounts, this kit addresses them; diagnose the cause before ordering, since a strut, spring, or bearing can produce similar symptoms.
