Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

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

3. Inspect the U-joints

Locate the U-joints at both ends of the driveshaft.
Check for any visible damage or excessive wear.
Use a pry bar to gently apply pressure to the U-joint and check for any play or movement.

4. Remove the Driveshaft (if necessary)

Using a socket set, remove the bolts securing the U-joint to the driveshaft and differential.
Carefully slide the driveshaft off the U-joint.

5. Replace the U-joint (if damaged)

Remove the clips or retainers holding the U-joint in place.
Use a U-joint press or a hammer to remove the old U-joint from the yoke.
Install the new U-joint by reversing the removal process, ensuring that it is properly seated.
Reinstall any clips or retainers and secure it with the appropriate torque specifications.

6. Reassemble

Reattach the driveshaft to the differential and torque the bolts to manufacturer specifications.
Reconnect the negative battery terminal.
