3. Remove U-joint

Sub-steps:
1. Using a U-joint puller, press the U-joint out of its yoke.
2. If necessary, use a hammer and socket to tap out the U-joint bearings.
3. Clean the yoke surfaces with a clean cloth to remove any debris or old grease.

4. Install New U-joint

Sub-steps:
1. Apply a small amount of grease to the new U-joint before installation.
2. Position the new U-joint into the yoke, ensuring proper alignment.
3. Use the U-joint puller to press the new U-joint into place securely.

5. Reinstall Driveshaft

Sub-steps:
1. Slide the driveshaft back into position, aligning it with the U-joint.
2. Reattach the bolts to the transmission and rear axle, tightening to the manufacturer’s specified torque (generally around 15-20 ft-lbs).
3. Ensure all components are secure and properly aligned.
