Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Raise the rear of the vehicle using a jack and secure it with jack stands.
Gather tools and parts required for the repair.

2. Remove Driveshaft

Tools Required: Socket set, torque wrench, universal joint puller
Remove the bolts securing the driveshaft to the rear differential and the transmission.
Support the driveshaft with one hand while removing the last bolt to prevent it from falling.
Carefully slide the driveshaft out of the transmission and set it aside.

3. Inspect and Replace U-Joints

Tools Required: U-joint press or universal joint puller, grease, clean rags
Remove the retaining clips from the U-joint caps using pliers.
Use the U-joint press to push out the old U-joint from the yoke.
Clean the yoke surfaces and apply a thin layer of grease to the new U-joint caps.
Install the new U-joint by pressing it into place and ensuring it's seated properly.
Reinstall the retaining clips securely to hold the U-joint in position.

4. Reinstall Driveshaft

Align the driveshaft with the transmission and rear differential, ensuring that the U-joint is properly seated in the yoke.
Reinstall the bolts and torque them to the manufacturer's specifications (typically around 40-50 ft-lbs, check the service manual for exact values).
Double-check that all connections are tight and secure.

5. Lower Vehicle and Test Drive

Remove the jack stands and lower the vehicle.
Conduct a test drive to ensure that the vibrations and noises have been resolved and that the vehicle operates smoothly.
