Dorman 986-083 Drive Shaft - Rear

Drive Shaft Assembly Overview

Dorman 986-083 is a complete drive shaft assembly built for direct replacement service. It arrives pre-balanced with new yokes, tubes, constant velocity joints, and universal joints to simplify driveline repair.

Compatible With Ram 2500 and Ram 3500 rear driveline applications, this aluminum drive shaft measures 74.625 inches in compressed length and uses a transmission yoke on one end with a flange on the other. The 986-083 part number is also referenced by 52123390AB for the same application.

Key Features

• Pre-balanced assembly for straightforward installation.
• Aluminum shaft construction with a 0.125-inch wall thickness.
• Transmission yoke and flange end configuration.
• Includes universal joints; CV joints are not included.
• Fixed-length design with no slip yoke and no adjustability.

Detailed Description

This Dorman drive shaft is engineered as a complete replacement for rear driveline service on Ram 2500 and Ram 3500 trucks. The assembly uses 100% new components in the yokes, tubes, and joints, which helps reduce the need to reuse worn driveline parts during repair. The 986-083 part number is a useful reference when matching the correct shaft configuration for 2010-2012 Ram truck applications.

The aluminum construction keeps the shaft lightweight while maintaining the specified diameter and wall thickness. Because the assembly is not adjustable and does not use a slip yoke, correct application matching is important before installation.

What It Helps Fix

• Driveline vibration caused by a worn or out-of-balance shaft.
• Clunking or looseness from worn universal joints.
• Damage to yokes, tubes, or shaft sections.
• Noise and driveline harshness from a failing rear shaft assembly.

Installation Notes and Tips

Verify the compressed length, end types, and rear application before installation. This shaft is not adjustable, so the existing driveline configuration must match the listed dimensions and connection style. Confirm fitment for 2010-2012 Ram 2500 and Ram 3500 rear applications before ordering.

Quality Assurance

Dorman supplies this drive shaft as a complete replacement assembly with new yokes, tubes, and joints for service-ready installation.
