1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and securely raise it with jack stands.
Disconnect the battery to ensure safety while working on the vehicle.

2. Remove Driveshaft

Tools Required: Socket set, torque wrench, pry bar.
Loosen and remove the bolts securing the driveshaft to the differential and the transmission.
Carefully slide the driveshaft out of the transmission and differential, ensuring not to damage any seals.

3. Inspect and Replace U-Joints

Inspect the U-joints for any play or damage.
If damaged, use a U-joint press to remove the old U-joint.
Install the new U-joint by aligning it properly and pressing it into place.

4. Reinstall Driveshaft

Slide the driveshaft back into the transmission and differential.
Torque Specification: Refer to the service manual for the appropriate torque values for the driveshaft bolts.
Securely tighten all bolts in a crisscross pattern to ensure even pressure.

5. Final Inspection

Recheck all connections and ensure there are no leaks from the differential or transmission.
