Product Details

Spicer 5-3218X is a greaseable universal joint engineered for driveline service where serviceability matters. The joint uses 1.062-inch bearing caps, 1.93-inch leg lengths, and an internal snap ring design to match the listed Nissan and INFINITI driveline applications. Dana Spicer designs, tests, and manufactures these components as part of an integrated OE-focused process, helping maintain the dimensional accuracy and durability expected in driveline repair.

This part cross-references SKF UJ446 for the same application. It is a direct-fit service part for select Nissan Pathfinder, INFINITI QX4, and Nissan D21 driveline positions when the original joint uses the same ISR-style configuration.

What It Helps Fix

• Driveline vibration from worn universal joint bearings
• Clunking or driveline lash during acceleration or deceleration
• Grease loss or dry-joint wear in serviceable driveshaft joints
• Need for replacement on front driveshaft or rear driveshaft positions
• Noise from looseness at the transfer case, front axle, transmission, support bearing, or rear axle locations
