• Description:

  This is a Ford W-prefix steering lower shaft bolt, a standardized fastener cataloged under part number W715479-S439 used to clamp the steering column lower or intermediate shaft to its yoke, with documented use across the Explorer, F-150, F-350 Super Duty, Aviator, Mark LT, Navigator, and Mountaineer. Dealer catalogs list it as a lower shaft upper bolt or steering shaft pinch bolt, and it replaces an earlier number. Because it is part of the steering connection, correct torque is essential; a loose or missing bolt lets the shaft joint move, producing steering play, knocking, and imprecise response. This is a single-use fastener that Ford specifies cannot be reused or reinstalled, so it should be replaced rather than refitted. The bolt is a standardized multi-application item rather than a single-model part, so no finite published vehicle list exists for it. Confirm the size and fitment against your VIN through a dealer parts catalog before ordering. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Part cannot be reused/reinstalled.
