Fitment and Application Details
Compatible with 2013-2018 Ram 3500, rear, Regular Chassis Cab. This Dorman 986-443 driveshaft is built for rear axle service on the Ram 3500 platform and is a practical OE-style replacement when the original shaft is worn, damaged, or out of balance. This part cross-references Mopar (e.g., 5146591AA) for the same application.
What This Drive Shaft Helps Address
- Vibration from a worn or unbalanced rear driveshaft
- Clunking or driveline noise from worn universal joints
- Service issues caused by damaged yokes or shaft tubing
- Fitment problems from a bent or incorrect-length replacement shaft
- Grease service needs on a maintainable driveline assembly
Installation Notes and Tips
Verify flange-to-flange measurements, compressed length, and overall length before installation. Confirm rear position fitment on 2013-2018 Ram 3500 Regular Chassis Cab models and inspect mating surfaces, hardware condition, and driveline angles during replacement. Because the assembly is adjustable in overall length, final alignment should be checked after installation.
Quality Assurance
Dorman supplies this drive shaft as a complete replacement assembly with new structural and joint components for service-ready installation. The pre-balanced design supports consistent driveline operation after replacement.
