Quiet a noisy, harsh front end with the KYB strut mount kit (P/N SM5424), a front suspension strut mount kit that replaces the old, hardened insulators transmitting road noise and vibration into the cabin. It installs as a direct-fit replacement for the front position on the 2003-2006 Ford Expedition, 2004-2008 Ford F-150, 2006-2008 Lincoln Mark LT and 2003-2005 Lincoln Navigator — see the Buyer's Guide tab for engine-level fitment.
The front bearing plates serve as the steering pivots and help support vehicle weight, so they are critical to steering feel and wheel alignment.
If worn, hardened front strut mounts are the cause of your noise, vibration or steering harshness, this kit replaces them. Have the vehicle diagnosed first, since these symptoms can have other causes.
