Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is on a flat surface, and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the drive components.

2. Remove the Drive Shaft

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the drive shaft to the differential and transmission using the socket set.
Carefully slide the drive shaft out, ensuring not to damage the surrounding components.

3. Inspect and Replace U-Joints

Check each U-joint for signs of wear, such as movement or damage.
If replacement is necessary, remove the retaining clips using pliers.
Use a press or hammer to carefully remove the old U-joint from the yoke.
Insert the new U-joint, ensuring it is aligned correctly, and reinsert the retaining clips.

4. Reinstall the Drive Shaft

Slide the drive shaft back into its original position.
Secure it by tightening the bolts to the manufacturer's specified torque using a torque wrench.

5. Final Checks

Reconnect the battery.
Lower the vehicle from the jack stands and perform a visual inspection to ensure everything is secure.
