4. Install New U-joint

Lubricate the new U-joint with appropriate grease, inserting it into the yoke.
Use the U-joint puller to press the new joint into place, making sure it is fully seated.
Repeat for the opposing side of the U-joint.

5. Reinstall Driveshaft

Align the driveshaft according to the marks made during removal.
Secure the driveshaft in place with the bolts, tightening to manufacturer-recommended torque specifications.
Recheck U-joint movement to ensure proper installation.

6. Test Drive

Lower the vehicle from the jack stands.
Conduct a test drive to ensure that vibrations or noises have been eliminated.
