Solution

1. Preparation

Gather tools and parts required for the repair.
Safely lift the vehicle using a jack and secure it with jack stands.
Disconnect the battery to ensure safety.

2. Remove Driveshaft

Sub-steps:
1. Remove the bolts securing the driveshaft to the differential and transmission using a socket set.
2. Carefully slide the driveshaft out of the U-joint yoke.
3. Support the driveshaft to prevent injury while disconnecting.

3. Replace U-joints

Sub-steps:
1. Using a U-joint removal tool, press out the old U-joint from the driveshaft.
2. Clean the U-joint sockets on the driveshaft.
3. Insert the new U-joint into the driveshaft and use the press tool to secure it in place.
4. Ensure that the U-joint is properly seated and lubricated.

4. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft with the transmission and differential.
2. Reinstall the bolts and torque them to the manufacturer’s specifications (typically around 20-30 ft-lbs).
3. Reconnect the battery once everything is secured.

5. Final Checks

Ensure that the driveshaft is correctly aligned and that there are no visible issues.
Lower the vehicle back to the ground.
