• Description:

  This is a genuine Ford standardized service nut carrying the W520217-S441 service number, a hex nut on the HM1 base most often cataloged as a suspension ball joint nut and sometimes supplied with a washer. Depending on the catalog you will also see it listed against a shock mount, a control arm, a strut or a tow hook. Real applications that share this exact service number include the Ford Expedition, F-150 and Maverick along with the Lincoln 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 ball joint nut that is loose, missing or reused past its clamp load lets the joint develop play, which shows up as a clunk over bumps, vague steering, uneven tire wear and a loss of secure suspension geometry. Because one service number is listed against several 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.
