  • OE series reference: Spicer 1310-WJ
  • Cross-reference: Four Seasons 20714

Built for Serviceable Front Axle Applications

This universal joint is engineered for front axle and drive shaft service where regular lubrication is part of maintenance. The grooved round bearing design and greaseable construction help support smoother operation in Jeep Cherokee, Jeep Wrangler, and Ford Bronco front axle applications, while also matching other front axle shaft positions listed in the fitment data. MOOG 378 is a practical replacement choice for vehicles that use the Spicer 1310-WJ style joint and require a 1-1/16 inch bearing diameter.

Common Problems This Part Can Address

  • Clunking or vibration from worn front axle universal joints
  • Need for a serviceable joint with grease access
  • Wear at the bearing caps from age, contamination, or heavy use
  • Front axle driveline looseness during acceleration or turning
  • Replacement needs on Jeep CJ5, CJ7, Wrangler, Cherokee, and Ford Bronco front axle shafts

Installation Notes and Tips

Verify bearing cap diameter, overall length, and OE series before installation. This part uses round grooved bearings and a flush-type lube fitting, so confirm the axle shaft and yoke style match the listed dimensions and snap-ring arrangement. For best results, clean the yoke bores thoroughly, inspect the retaining grooves, and grease the joint after installation according to the vehicle service procedure.

Quality Assurance

MOOG backs this universal joint with materials selection and testing focused on consistent performance in driveline service. The brand’s problem-solving design approach is reflected in the serviceable construction and OE-series matching used for this part.
