Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during the repair.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove Driveshaft

Use a socket set to remove the bolts securing the driveshaft to the differential and transfer case.
Support the driveshaft while removing the last bolts to prevent it from dropping suddenly.

4. Inspect and Replace U-joint

Use a U-joint puller to remove the old U-joint from the driveshaft.
Clean the area where the new U-joint will be installed.
Apply a light coating of grease to the new U-joint and install it using the puller.
Ensure that the U-joint cups are seated properly in their respective positions.

5. Reinstall Driveshaft

Align the driveshaft with the differential and transfer case, ensuring proper orientation.
Secure the driveshaft with the previously removed bolts, tightening them to the manufacturer’s specified torque (usually around 15-25 ft-lbs, but verify with the service manual).

6. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the battery.
