Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Raise the Vehicle

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

3. Remove Driveshaft

Using a socket set, remove the bolts securing the driveshaft to the U-joint on both ends.
Carefully slide the driveshaft out of the transmission and the rear differential, taking note of the orientation for reinstallation.

4. Replace U-joint

Secure the driveshaft in a vice to prevent movement while working on it.
Use a U-joint removal tool or a hammer and punch to remove the old U-joint by driving out the retaining clips and bearing caps.
Clean the area thoroughly where the U-joint sits.
Lubricate the new U-joint and install it into the driveshaft, ensuring that it is seated properly.
Reinstall the retaining clips and ensure they are secure.

5. Reinstall Driveshaft

Align the driveshaft with the transmission and rear differential.
Reinstall the bolts and tighten them to the manufacturer’s specified torque settings (typically around 30-40 Nm, but check specific values for your model).
Ensure the driveshaft is properly aligned.

6. Lower Vehicle and Reconnect Battery

Carefully remove the jack stands and lower the vehicle.
Reconnect the battery terminals.
