Apply grease to the new U-joint and press it into the driveshaft yoke using the removal tool.
Ensure that the U-joint is properly seated and that the retaining clips are securely in place.

5. Reinstall Driveshaft

Position the driveshaft back into the transmission and rear differential.
Torque the driveshaft bolts to the manufacturer’s specifications (consult repair manual for specific torque values).
Reconnect the battery.
