Product Details

Dorman 946-113 is a complete rear drive shaft assembly for Ram 1500 and Dodge Ram 1500 trucks with one-piece shaft configurations. It is pre-balanced for installation and uses 100% new yokes, tubes, CV joints, and universal joints to restore driveline function without rebuilding the original shaft. The aluminum construction and fixed-length design support a straightforward replacement for the specified rear driveline application.

This part cross-references OE number 68034551AA for the same application. It is a practical choice for Ram 1500 rear drive shaft replacement when the original shaft is damaged, worn, or no longer running smoothly.

What It Helps Fix

• Driveline vibration from a worn or out-of-balance shaft
• Clunking or driveline noise during acceleration or deceleration
• Damage to the original shaft tube, yokes, or joints
• Loss of smooth power transfer to the rear axle
• Replacement needs on Ram 1500 rear one-piece shaft assemblies

Installation Notes

Verify rear-position fitment and one-piece shaft assembly requirements before installation. Confirm shaft length, slip yoke configuration, and OE reference 68034551AA against the vehicle before removal of the original part. Because this assembly is not adjustable, correct application matching is important for proper driveline alignment.
