Product Details

The Dana Spicer 5-1301X universal joint is built for driveline repair where the rear driveshaft at rear axle connection needs the correct cap diameter, snap ring style, and overall span. The FSGR line focuses on serviceable driveline components for light vehicle, commercial, and off-highway use, and this joint follows that approach with a greaseable cross and steel body for routine maintenance access. If you are servicing a Dodge W300 or Dodge W350 rear driveshaft at rear axle, the 5-1301X provides the listed ISR-style dimensions needed for the application.

This part cross-references SKF UJ304 for the same application.

Common Problems This Part Can Address

• Driveline vibration from worn universal joint bearings
• Clunking or driveline lash during acceleration or deceleration
• Need for a serviceable joint with a grease fitting
• Fitment issues caused by incorrect bearing cap diameter or snap ring style
• Rear driveshaft wear at the rear axle connection on Dodge W300 and Dodge W350 trucks

Installation Notes and Tips

Verify bearing cap diameters, inside snap ring dimension, and ISR-style configuration before installation. This joint is listed for 1982-1988 Dodge W350 rear driveshaft at rear axle applications with a 1-piece driveshaft, for 1981 Dodge W350 rear driveshaft at rear axle applications with a 2-piece driveshaft, and for 1978-1980 Dodge W300 rear driveshaft at rear axle applications with a 2-piece driveshaft. Confirm the driveshaft and axle-side dimensions against the removed part before pressing in the new joint.

Use the grease fitting to service the joint after installation and during routine maintenance intervals. The internal snap ring design requires the correct retaining hardware and proper seating in the yokes.
