• Description:

  This is a genuine Ford standardized service locking nut carrying the W520214-S442 service number, an M12 nut on the HM1 base most often cataloged as an upper control arm lock nut. Depending on the catalog you will also see it listed against a shock mount, an engine mount, a steering knuckle or a strut. Real applications that share this exact service number include the Ford Bronco, Explorer, Fusion and Escape along with the Police Responder Hybrid, 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 control arm lock nut that is loose, missing or reused past its clamp load lets the arm or joint shift, which shows up as a clunk over bumps, alignment that drifts, uneven tire wear and vague steering. 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 not reusable, replace only.
