• Description:

  This is a genuine Ford standardized service nut carrying the W520113-S440 service number, built on the HN1 base and most often cataloged as a stabilizer bar nut. It replaces the earlier S427 revision and is also listed against a frame crossmember, a running board or a seat belt anchor. Real applications that share this exact service number include the Ford Crown Victoria, E-350 and F-150 along with the Lincoln Mark LT and Navigator, and it appears on other bodies because Ford consolidates common threaded hardware under one number. This is a single-use fastener that Ford specifies cannot be reused or reinstalled once loosened, and a fresh one should be fitted on reassembly. A nut of this kind that is loose, missing or reused past its clamp load lets the stabilizer bar or anchored component shift, which can present as a clunk over bumps, vague handling or a loose attachment. Because one service number is listed against many model years and configurations, confirm the exact fit for your vehicle against your VIN before ordering so the thread size matches the stud you are servicing.
