Solution

1. Preparation

Gather all 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

Using a jack, lift the vehicle and place it securely on jack stands.
Make sure the vehicle is stable before proceeding.

3. Remove the Driveshaft

Using a socket set, remove the bolts securing the drive shaft to the rear differential and the transmission.
Carefully slide the drive shaft out of the transmission and set it aside.

4. Inspect and Replace U-joint

Use a U-joint removal tool to press the old U-joint out of the yoke.
Align the new U-joint and press it into place using the U-joint tool.
Ensure that the U-joint clips are installed correctly and that they snap into place.

5. Reinstall Driveshaft

Position the driveshaft back into the transmission and secure it with bolts.
Torque the bolts to the manufacturer's specifications (typically around 15-20 ft-lbs, but check service manual for exact specs).

Reconnect the battery and ensure all electrical connections are secure.
