Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, mechanic's creeper, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged. Disconnect the battery if necessary for safety.

2. Raise the Vehicle

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

3. Remove the Driveshaft

Tools Required: Socket set.
Remove the bolts securing the driveshaft to the rear differential and the transmission.
Carefully slide the driveshaft out of the transmission and lower it from the vehicle.

4. Inspect the U-joint

Examine the U-joint for any signs of wear, such as rust, cracks, or excessive play.
Attempt to rotate the U-joint by hand; it should move smoothly without binding.

5. Replace the U-joint (if necessary)

Tools Required: U-joint removal tool, grease, socket set.
Use a U-joint removal tool to press out the old U-joint from the yoke.
Clean the yoke and install the new U-joint, ensuring it is seated properly.
Apply grease to the new U-joint as per manufacturer specifications.

6. Reinstall the Driveshaft

Reinsert the driveshaft into the transmission and align it with the rear differential.
Secure the driveshaft with the bolts and torque them to the manufacturer's specifications (typically around 30-50 ft-lbs, but check the manual for exact numbers).

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Reconnect the battery if it was disconnected.
