Detailed Description

This Dorman drive axle shaft is built for front differential service on 2012-2018 Ram 1500 and 2019-2022 Ram 1500 Classic models with Sales Code DMD (3.55 axle ratio). It replaces the failed inner axle shaft directly, helping restore driveline operation on Ram 1500 front axle assemblies that do not offer the OE shaft as a separate service part. Part number 630-011 is a practical repair option when the original shaft is worn, damaged, or no longer serviceable.

The shaft is made from carbon steel and finished in galvanized coating for added corrosion resistance. It measures 18.5 inches long, 30.8 mm in diameter, and uses a solid shaft axle design with an IFS differential case type. Package contents include bearings, a 4WD collar, dust shield, inner axle shaft, O-ring, and axle seal.

This part cross-references OE number 68257421AG for the same application.

What It Helps Fix

• Front axle shaft failure in Ram 1500 4WD trucks
• Noise or vibration from a worn inner axle shaft
• Loss of front differential function caused by shaft damage
• Repair needs where the OE shaft is not sold separately
• Replacement needs after salvage-yard parts are no longer a good option

Installation Notes and Tips

• Verify Sales Code DMD and 3.55 axle ratio before ordering.
• Confirm front-position fitment for your Ram 1500 or Ram 1500 Classic.
• Inspect related seals and bearings during service to help prevent repeat failure.
• Match spline count and shaft dimensions to the original assembly before installation.
