Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- U-joint puller
Lift the vehicle securely using a jack and support with jack stands. Ensure the vehicle is on a level surface.

2. Remove Driveshaft

Sub-steps:
1. Disconnect the Battery: Prevent any electrical issues while working.
2. Remove Bolts: Using the socket set, remove the bolts connecting the driveshaft to the differential and transmission.
3. Slide Out Driveshaft: Carefully slide the driveshaft out of the transmission or differential.

3. Inspect U-joints

Sub-steps:
1. Check for Movement: Attempt to move each U-joint by hand; there should be minimal play.
2. Look for Cracks or Wear: Inspect for any visible cracks or wear on the U-joint caps and cross.
3. Check for Grease: Ensure there is adequate grease in the U-joint; lack of grease indicates potential wear.

4. Replace Worn U-joints

Sub-steps:
1. Use U-joint Puller: If U-joints are worn, use the U-joint puller to remove them from the driveshaft.
2. Install New U-joints: Align new U-joints and press them into place securely.
3. Reinstall Driveshaft: Slide the driveshaft back into position and secure with bolts, tightening to the manufacturer's torque specifications.

5. Reconnect Battery and Test Drive

Reconnect the battery and perform a test drive to check for any noise or vibrations.
