Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, grease gun.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety during the repair.

2. Raise the Vehicle

Use a jack to lift the vehicle until it is high enough to access the driveshaft.
Secure the vehicle on jack stands to ensure stability.

3. Remove the Driveshaft

Using a socket set, remove the bolts securing the driveshaft to the U-joint.
Carefully slide the driveshaft out of the U-joint and set it aside.

4. Inspect and Replace the U-joint

Check the U-joint for signs of wear or damage.
If replacement is necessary, use a U-joint puller to remove the old U-joint from the driveshaft.
Apply lubrication to the new U-joint, ensuring that it fits snugly into the driveshaft.

5. Reinstall the Driveshaft

Align the driveshaft with the U-joint and secure it with the bolts.
Use a torque wrench to tighten the bolts to the manufacturer’s specified torque value.

6. Lower the Vehicle

Remove the jack stands and carefully lower the vehicle back to the ground.
Reconnect the battery once the repair is complete.
