Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety.

2. Lift the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure with jack stands to prevent any accidental lowering.

3. Remove the Driveshaft

Use a socket set to remove the bolts securing the driveshaft to the rear differential and transmission.
Carefully slide the driveshaft off the U-joint, supporting it to avoid damage.

4. Inspect and Replace the U-joint

Examine the U-joint for any visible wear, rust, or damage.
If replacement is needed:
1. Use a U-joint removal tool to press out the old U-joint.
2. Clean the area and apply grease to the new U-joint.
3. Position the new U-joint in place and press it in using the removal tool.

5. Reinstall the Driveshaft

Align the driveshaft with the U-joint and secure it using the previously removed bolts.
Torque the bolts to the manufacturer's specifications (typically around 30-50 lb-ft, but verify with a service manual).

6. Lower the Vehicle and Test Drive

Remove the jack stands and lower the vehicle.
Reconnect the battery.
Perform a test drive to ensure the issue has been resolved.
