Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during repair.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the F-150.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Driveshaft

Using a socket set, remove the bolts securing the driveshaft to the rear differential and the transmission.
Carefully slide the driveshaft out, noting its orientation for reinstallation.

4. Inspect and Replace the U-Joint

Secure the driveshaft in a vice if necessary.
Use a U-joint removal tool to press out the old U-joint from the driveshaft yoke.
Clean the yoke surfaces where the new U-joint will be installed.
Apply grease to the new U-joint and install it into the yoke, ensuring proper alignment.
Press the new U-joint into place using the U-joint tool, ensuring it is seated correctly.

5. Reinstall the Driveshaft

Align the driveshaft with the previously noted orientation.
Reinstall bolts to secure the driveshaft to both the rear differential and the transmission. Torque the bolts to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Reconnect the battery.
