• Description:

  This genuine Ford nut, part number W711310-S440, is a rear lower control arm nut used on the F-150 and related Lincoln platforms to secure the lower control arm at its pivot. It threads onto the control arm bolt to clamp the arm to its bracket, locating the suspension member so it stays fixed under load and the geometry remains correct. Buyers search for this nut when replacing a control arm or bushing, since the original may be corroded, stretched, or discarded and the joint must be clamped to specification. A loose or missing control arm nut lets the arm shift, causing alignment drift, clunking over bumps, or uneven tire wear. Ford lists this as a genuine control arm nut, and using the OEM part ensures the correct thread and clamp so the arm is held securely. Installing the proper nut restores secure arm mounting and stable alignment. Torque to the published specification with the suspension at ride height where required, hold the bolt from turning while tightening, and inspect the threads before reuse, replacing the nut if it shows damage so the joint holds reliably over the life of the suspension.

• Notes: Part cannot be reused/reinstalled.
