2. Remove Driveshaft

Locate the U-joint connection points on the driveshaft.
Using a socket set, remove the bolts securing the driveshaft to the differential and transmission.
Carefully slide the driveshaft out of the U-joint while keeping it supported to avoid damage.

3. Inspect and Replace U-joint

Use the U-joint removal tool to remove the old U-joint from the driveshaft and the yoke.
Clean the mating surfaces on the driveshaft and yoke to ensure a proper fit for the new U-joint.
Install the new U-joint into the driveshaft and yoke, ensuring it is aligned correctly.
Secure the U-joint with the retaining clips or bolts as per the manufacturer's specifications.

4. Reinstall Driveshaft

Position the driveshaft back into place, ensuring proper alignment with the transmission and differential.
Reattach the driveshaft using the bolts removed earlier, torquing them to the manufacturer's specifications.

5. Final Checks

Reconnect the battery.
Lower the vehicle and perform a final inspection of all connections.
Conduct a road test to ensure that the symptoms are resolved.
