Right Front CV Intermediate Shaft Repair

Dorman 630-446 is a right front intermediate CV shaft for select Ram 1500 and Ram 1500 Classic 4WD pickups with Sales Code DMD and a 3.55 axle ratio. It addresses a known spline-failure condition on the front differential side and restores driveline function without replacing the complete differential assembly.

Key Features

  • Direct replacement right front intermediate CV shaft for the front outer position
  • Steel construction with a black finish
  • Includes bearings, clips, seals, dust shield, axle shaft seal, and O-ring for the repair
  • Splined inboard and outboard ends for OE-style engagement
  • OE FIX solution for Ram 1500 front differential service where the original shaft is not sold separately

Detailed Product Overview

This Dorman 630-446 intermediate shaft is built for 2012-2020 Ram 1500 and 2019-2021 Ram 1500 Classic models in the front right outer position with Sales Code DMD (3.55 axle ratio). It replaces a failed intermediate CV shaft that can be damaged when the axle moves past the retaining ring and the splines are compromised. For Ram 1500 and Ram 1500 Classic owners, this part provides a direct repair path for the front differential side without sourcing a complete differential assembly or salvage-yard component.

The shaft measures 11.5 inches compressed/extended length, uses a 16-spline inboard end and 29-spline outboard end, and is supplied with the service components needed to complete the repair. Part number 630-446 is also referenced by OE number 68257421AG for the same application.

What This Part Helps Repair

  • Front right intermediate shaft spline failure
  • Loss of driveline engagement at the front differential
  • Damage caused by axle movement past the retaining ring
  • Need to replace a front differential-side shaft that is not sold separately by OE
  • Repair needs on Ram 1500 and Ram 1500 Classic 4WD trucks with the 3.55 axle ratio

Installation Notes and Tips

Verify Sales Code DMD and axle ratio before ordering. Confirm the vehicle is a 4WD Ram 1500 or Ram 1500 Classic and match the front right outer position exactly. Inspect the retaining ring, seals, and bearing surfaces during installation, and replace any worn mating components before reassembly. Proper spline alignment and clean sealing surfaces are important for a durable repair.
