Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to ensure safety while working on the drivetrain.

2. Lift the Vehicle

Use a floor jack to lift the rear of the vehicle securely.
Place jack stands under the vehicle to support it safely.
Remove the rear wheels for better access if necessary.

3. Remove the Driveshaft

Mark the position of the driveshaft for reinstallation.
Use a socket set to remove the bolts securing the driveshaft to the differential and transmission.
Carefully slide the driveshaft out of the U-joint and remove it from the vehicle.

4. Inspect and Replace U-joint

Check the U-joint for any signs of wear, including excessive play or rust.
If replacement is necessary, use a U-joint removal tool to press the old U-joint out of the yoke.
Clean the yoke and prepare it for the new U-joint installation.

5. Install New U-joint

Grease the new U-joint with appropriate lubricant.
Carefully press the new U-joint into the yoke using the U-joint tool.
Ensure proper alignment and secure it with retaining clips or bolts as required.

6. Reinstall Driveshaft

Align the marked position of the driveshaft and install it back onto the transmission and differential.
Torque the bolts to the manufacturer’s specifications (consult the service manual for exact torque values).
Reinstall the wheels if they were removed.

7. Lower Vehicle and Final Checks

Remove jack stands and lower the vehicle.
Reconnect the battery and start the engine to check for proper operation.
