Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, wrench set, grease gun, U-joint puller or press.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during the repair.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure safety by verifying that the vehicle is stable before proceeding.

3. Remove Driveshaft

Remove the bolts securing the driveshaft to the rear differential and the transmission using the appropriate socket size.
Carefully slide the driveshaft out of the U-joint connection and set it aside.

4. Replace U-joints

Remove Old U-joints:
- Use a U-joint puller or press to remove the old U-joints from the driveshaft.
- Be cautious with the driveshaft to prevent bending or damage.
Install New U-joints:
- Lubricate the new U-joints with grease.
- Press the new U-joints into place using the U-joint press.
- Ensure that they are seated properly and rotate freely.

5. Reinstall Driveshaft

Align the driveshaft with the differential and the transmission.
Reattach the bolts to secure the driveshaft, tightening them to the manufacturer’s specified torque values (usually between 15-20 ft-lbs; check service manual for specifics).

6. Final Checks

Reconnect the battery.
Lower the vehicle from the jack stands.
Check the U-joint movement by hand to ensure it operates freely and smoothly.
