Specs At A Glance

Good To Know

Q: How do I know if my support bearing needs replacement? A: Symptoms include a rhythmic thumping or clunking noise from under the truck, especially when accelerating or decelerating. Vibration felt through the floor or seat at certain speeds also points to a worn center support bearing.

Q: Can I replace just the U-joints and keep the old bearing? A: It is recommended to replace the support bearing and U-joints together as a kit, because wear on one component typically accelerates wear on the others. Replacing all at once ensures the driveshaft assembly operates as a balanced unit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
