Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure it with jack stands to prevent any accidents.

3. Remove Driveshaft

Tools Required: Socket set, torque wrench.
Remove the bolts securing the driveshaft to the differential and transmission (torque specifications typically between 45-60 Nm).
Slide the driveshaft out of the U-joint connections.

4. Inspect and Replace U-Joint

Check the U-joint for play by manually moving it; if there is excessive movement, replacement is necessary.
Tools Required: U-joint puller, grease gun (if applicable).
Remove the retaining clips holding the U-joint in place.
Use the U-joint puller to extract the old U-joint from the yoke.
Insert the new U-joint, ensuring it is seated properly.
Reinstall the retaining clips securely.

5. Reinstall Driveshaft

Slide the driveshaft back into position and secure it with the bolts.
Torque the bolts to manufacturer specifications (usually between 45-60 Nm).

6. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Reconnect the battery.
