  Suspension Track Bar Bolt, Bolt

• Description:

  This is a genuine Ford track bar bolt built on the HB1 base, the bolt Ford specifies to secure the suspension track bar to the axle bracket and frame mount. Documented applications include E-550, F-350 Super Duty, and F-550 Super Duty across all-wheel-drive, four-wheel-drive, and rear-wheel-drive configurations, and the part replaces W706345-S436, confirming it as a superseding multi-vehicle service bolt. The track bar locates the axle laterally, so its mounting bolt carries significant load and must hold clamp force against constant suspension motion. A loose, stretched, or corroded track bar bolt lets the axle shift side to side, which produces a wandering or loose steering feel, a clunk over bumps, and uneven tire wear. Because the joint is suspension-critical and the bolt sees high cyclic load, the OEM bolt torqued to specification is the right choice. Confirm the track bar hardware callout for your chassis and drivetrain against your VIN before ordering so the bolt length and grade match your application. This is a multi-year service part that fits across the model years of the listed Ford applications.
