Dana Spicer 5-3230X Universal Joint - Rear Driveshaft at Rear Axle, Rear Driveshaft at Support Bearing or Rear Driveshaft at Transmission

OE-Style Universal Joint for Ram and Dodge

The Dana Spicer 5-3230X is an OSR-style universal joint built for rear driveshaft service on select Ram and Dodge heavy-duty trucks. It uses 1.375-inch bearing caps, a 4.946-inch outside snap ring dimension, and a non-greasable steel design for direct replacement in AAM 1555 series driveline applications.

Built under the Dana Spicer FSGR line, this joint reflects the brand’s OE-focused engineering and manufacturing approach for driveline components. If you are servicing a 2007-2012 Ram 3500 or a 2007-2008 Dodge Ram 3500 rear driveshaft, the 5-3230X is the type of replacement part commonly specified for those exact configurations.

Common Repair Uses

• Driveline vibration from worn bearing surfaces
• Clunking or driveline lash during acceleration and deceleration
• Need for a direct replacement on Ram 3500 rear driveshaft service
• Replacement of a damaged or seized universal joint in AAM 1555 applications
• Restoring smooth power transfer in Dodge Ram 3500 and Ram 3500 drivetrains

Installation Notes and Tips

Verify the bearing cap diameter, outside snap ring dimension, and driveshaft location before ordering. This Dana Spicer 5-3230X uses external snap rings and is specified for OSR-style applications, so the retaining style must match the original driveline setup. Confirm whether the truck uses a 1-piece or 2-piece driveshaft and whether the joint is located at the transmission, support bearing, or rear axle.

For best results, inspect the yoke bores, snap ring grooves, and companion driveline components during installation. Proper seating of the caps and snap rings is critical to maintaining correct joint alignment in Ram 3500 and Dodge Ram 3500 rear driveshaft service.

Quality Assurance

Dana Spicer manufactures driveline components with design, testing, and production processes aligned to OE requirements. The 5-3230X is built as a genuine Spicer replacement for AAM 1555 series applications, with steel construction and non-greasable operation for consistent service in the specified fitments.
