• Description:

  This is a genuine Ford bolt cataloged as a front upper control arm bolt, documented on the Ford Expedition and the related Lincoln Navigator front suspension across multiple model years. It fastens the upper control arm to the frame, locating the arm so the front geometry and alignment stay within specification under load. Because it carries suspension loads and helps set wheel position, the bolt is torqued to a defined value and Ford treats it as a single use fastener that should be replaced rather than reused once disturbed. A worn, corroded or under torqued upper arm bolt can let the control arm shift, which a driver may notice as a clunk over bumps, a steering pull, uneven or accelerated tire wear, or an alignment that will not hold after adjustment. Replacing the bolt whenever the upper arm or bushing is serviced restores correct clamp load and keeps the arm located through its full range of travel. The bolt has a specific thread size, length and grade matched to the upper control arm and frame bracket, so the correct part is important. Confirm this bolt against your Expedition or Navigator VIN or a Ford parts diagram before ordering so the thread, length and grade match your front suspension.

• Notes: Part cannot be reused/reinstalled.
