Solution

1. Preparation

Tools Required:

Remove Bolts:
- Use the socket set to remove the bolts securing the driveshaft to the differential and the transmission.
Disconnect Driveshaft:
- Carefully slide the driveshaft out of the transmission or differential, ensuring not to damage any seals.

3. Inspect and Replace U-Joint

Inspect U-Joint:
- Visually inspect the U-joint for wear or damage.
Remove U-Joint:
- If replacement is necessary, use the U-joint puller tool to remove the old U-joint from the driveshaft.
Install New U-Joint:
- Lubricate the new U-joint with grease and press it into place using the U-joint tool.
Secure U-Joint:
- Ensure the U-joint is secured with the retaining clips and correctly aligned.

4. Reinstall Driveshaft

Reinsert Driveshaft:
- Slide the driveshaft back into place, ensuring it is properly aligned with both the transmission and differential.
Secure Bolts:
- Reinstall and torque all bolts to the manufacturer’s specifications, usually around 20-30 ft-lbs, but check the service manual for exact values.

5. Final Checks

Lower Vehicle:
- Remove jack stands and lower the vehicle.
Check for Noise:
