• Description:

  This Genuine Ford rear control arm mount bolt (W712774-S900) is documented for Ford Expedition and Lincoln Navigator across multiple model years. This is a Genuine Ford rear control arm mount bolt in an M18-class size, the large fastener that secures a rear suspension control arm at its body or subframe mount. 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 a rear control arm mount bolt, and dealer parts data also shows it as an upper or lower control arm mount bolt. When this bolt is loose or worn the rear arm develops play, producing clunking over bumps, alignment drift, rear-end wander and accelerated bushing and tire wear. Correct torque keeps the arm located so the rear suspension tracks properly. 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.
