Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Lift the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure it with jack stands for safety.

3. Remove Driveshaft

Tools Required: Socket set, torque wrench, penetrating oil
Remove the bolts securing the driveshaft to the rear differential and the transmission.
Carefully pull the driveshaft away from the U-joint area. If it’s stuck, apply penetrating oil and gently tap it free.

4. Remove Old U-Joint

Secure the driveshaft in a vise or on a workbench.
Use a U-joint removal tool or a hammer and socket to push out the old U-joint from the yoke.
Clean any debris or rust from the yoke using a wire brush.

5. Install New U-Joint

Parts Required: New U-joint
Apply grease to the new U-joint and insert it into the yoke.
Use the U-joint tool to press the new U-joint into place.
Ensure that the U-joint is seated properly and that there are no gaps.

6. Reinstall Driveshaft

Align the driveshaft back to the transmission and rear differential.
Install and torque the bolts to the manufacturer’s specifications (usually around 30-50 lb-ft, but check service manual).
Ensure that the driveshaft is balanced and properly aligned before tightening.

7. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
