Solution

1. Preparation

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

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Place jack stands under the vehicle to secure it.

3. Remove Driveshaft

Tools Required: Socket set, universal joint puller, torque wrench
Remove the bolts securing the driveshaft to the differential and transmission.
Carefully slide the driveshaft out of the transmission and differential.

4. Inspect U-Joints

Visually inspect the U-joints for any signs of corrosion, wear, or damage.
Attempt to wiggle the U-joints to check for any play; they should move smoothly without excessive looseness.

5. Replace U-Joints (if necessary)

If any U-joint is found to be defective, proceed with replacement:
- Tools Required: U-joint press, grease gun, clean rags
- Use a U-joint press to remove the faulty U-joint from the driveshaft.
- Install the new U-joint, ensuring proper orientation.
- Grease the new U-joint using a grease gun until it is filled, then clean any excess grease.

6. Reinstall Driveshaft

Align the driveshaft with the transmission and differential.
Reinstall the mounting bolts and tighten them to the manufacturer's specified torque values.

7. Lower the Vehicle

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