• Description:

  This genuine Ford suspension strut nut, catalogued under base number 15151, threads onto the front strut mounting studs on the F-150 to clamp the upper strut mount to the body. It is a flanged locking nut that holds the damper assembly located and preloaded against the strut tower, keeping the front corner geometry stable as the suspension cycles. Ford lists it as a one-time-use fastener, because the locking feature and the clamp load are critical to keeping the strut mount from working loose under repeated suspension travel. A buyer searching for this part is usually replacing front struts, mounts, or coil springs, chasing a clunk or knock from the strut tower over bumps, or replacing nuts that were removed and should not be reused. Built to Ford specifications, it provides the correct thread and flange bearing surface to seat against the mount and reach proper torque. Because reusing a spent locking nut risks loosening, fresh nuts should be installed whenever the strut mount is disturbed, and each should be torqued to the value in the front suspension procedure. Confirm the strut mount is fully seated on the tower before tightening so the studs draw down evenly and the alignment is preserved.

• Notes: Part cannot be reused/reinstalled.
