Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with jack stands.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Driveshaft

Tools Required: Socket set, torque wrench, penetrating oil.
Remove the bolts securing the driveshaft to the differential and transmission (use penetrating oil if bolts are rusted).
Carefully slide the driveshaft out of the transmission or differential.

3. Replace U-joints

Inspect the U-joints for wear; if needed, replace them.
Tools Required: U-joint press or hammer, snap ring pliers.
Remove the retaining clips/snap rings from the U-joint.
Use the U-joint press to remove the old U-joint from the yoke.
Insert the new U-joint and secure it with retaining clips/snap rings.

4. Reinstall Driveshaft

Align the driveshaft with the markings made during removal.
Reattach the driveshaft to the differential and transmission.
Torque Specification: Tighten bolts to manufacturer's specified torque (check vehicle service manual for exact value).

5. Final Checks
