Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- U-joint puller or press
- Safety glasses and gloves
Ensure the vehicle is on a flat surface and secure it with wheel chocks. Raise the vehicle using a jack and support it with jack stands.

2. Remove Driveshaft

Sub-steps:
1. Disconnect the rear driveshaft from the rear differential by removing the bolts using the socket set.
2. Mark the position of the driveshaft relative to the differential for reinstallation.
3. Remove the front U-joint bolts from the transmission using the socket set.
4. Carefully slide the driveshaft out of the transmission and out from under the vehicle.

3. Inspect U-joints

Sub-steps:
1. Visually inspect the U-joints for any cracks, rust, or signs of wear.
2. Check for any play in the U-joint by attempting to move the cross with your hands; any excessive movement indicates wear.
3. If the U-joint is damaged, proceed to replace it.

4. Replace U-joint (if necessary)

Sub-steps:
1. Using a U-joint puller or press, remove the damaged U-joint from the driveshaft.
2. Install the new U-joint by pressing it into place, ensuring it is seated correctly.
3. Reinstall the driveshaft by aligning the marks made earlier and securing it to the rear differential and transmission with the original bolts.
4. Torque the bolts to the manufacturer’s specifications (refer to the service manual for specific torque values).

5. Reassemble and Lower Vehicle

Sub-steps:
1. Double-check all connections and ensure everything is secured.
2. Carefully lower the vehicle back to the ground and remove wheel chocks.
