• Description:

  This is a genuine Ford standardized service nut carrying the W520215-S441 service number, a flanged hex nut on the HN1 base most often cataloged as an upper control arm nut. Depending on the catalog you will also see it listed against an outer tie rod, a leaf spring, a U-bolt, a stabilizer link or a lower control arm. Real applications that share this exact service number include the Ford F-150 and Expedition along with the Lincoln Navigator and MKZ, 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 control arm, spring or joint on its stud shift, which shows up as a clunk over bumps, alignment that drifts and handling that feels looser than normal. 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.

• Notes: Part cannot be reused/reinstalled.
