2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Make sure the vehicle is stable before working underneath it.

3. Remove the Driveshaft

Tools Required: Socket set, torque wrench, penetrating oil
Remove any protective covers or heat shields that may obstruct access to the driveshaft.
Use penetrating oil on the bolts to ease removal.
Remove the bolts securing the driveshaft to the U-joint and transmission.
Carefully lower and remove the driveshaft from the vehicle.

4. Inspect and Replace the U-Joint

Tools Required: U-joint puller, hammer, press, grease
Inspect the U-joint for wear or damage. If any play or damage is found, proceed with replacement.
Use a U-joint puller or hammer to remove the old U-joint from the driveshaft.
Clean the area where the new U-joint will be installed.
Install the new U-joint by pressing it into place. Ensure it is seated properly.

5. Reinstall the Driveshaft

Align the driveshaft back into position with the U-joint.
Secure it with the bolts, following the manufacturer’s torque specifications.
