Simplify your rear driveshaft replacement with the Dorman drive shaft 946-844, a rear 2-piece steel driveshaft assembly that is a direct fit for the 2003-2007 Ford F-350 Super Duty (engine: All).

A rear driveshaft carries torque back to the rear axle. If worn U-joints or a damaged shaft are behind driveline vibration, a clunk when shifting into gear, or squeaking from under the truck, this assembly is designed to replace the failed driveshaft.

  • Ready to install: ships fully assembled and dynamically pre-balanced for a quick installation on the listed application.
  • Shaft tubing: drawn over mandrel (DOM) seamless steel tubing offers superior concentricity, uniform wall thickness, and greater torsional strength and dent resistance than standard welded steel.
  • All-new construction: the tubing, yokes, CV joints, and U-joints are 100% new components.
  • Protective packaging: ships in foam-in-place packaging designed to keep the assembly in install-ready condition during transit.
