• Description:

  This Genuine Ford upper control arm bolt (W712104-S439) is documented for Ford Expedition, F-150 and Lincoln Navigator across multiple model years. This is a Genuine Ford upper control arm bolt, a fastener used to secure an upper control arm or, in some applications, a shock lower mount to its bracket. It uses the standard Ford W-series bolt base and is a multi-vehicle suspension service part shared across many platforms rather than one model. Ford lists it as an Upper Control Arm Bolt, and dealer parts data also shows it as a control arm pivot bolt or shock lower bolt. When this bolt is loose or worn the arm or shock develops play, producing clunking over bumps, alignment drift, wandering steering and accelerated tire and bushing wear. Correct torque keeps the part located so suspension geometry stays true. Ford service procedures specify this fastener as single-use; it is torqued to a yield-controlled spec and must be replaced rather than reused once removed, so plan on a fresh piece any time the joint is disturbed. Ford does not publish a finite vehicle list for this universal hardware item, so confirm the exact application against your VIN before ordering so the thread, length and grade match, and have alignment checked after installation.

• Notes: Part cannot be reused/reinstalled.
