Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent the vehicle from rolling.
Disconnect the battery to ensure safety while working on the driveshaft.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Pry bar
U-joint removal tool or hammer

2. Lift the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Driveshaft

Using a socket, remove the bolts securing the driveshaft to the rear differential and transmission.
Carefully slide the driveshaft out of the transmission and differential.

4. Inspect and Test U-Joints

Use a pry bar to check for play in the U-joints by attempting to move them in various directions.
If any play is detected, the U-joint is likely worn and should be replaced.
Check the lubrication by ensuring that the grease fittings are accessible and not clogged.

5. Replace U-Joint (if necessary)

If replacement is needed, use a U-joint removal tool to press out the old U-joint.
Clean the area thoroughly before installing the new U-joint.
Press in the new U-joint and ensure it is seated properly.

6. Reassemble Driveshaft

Reinstall the driveshaft to the transmission and differential.
Torque the bolts to the manufacturer's specifications (usually around 30-50 Nm, but verify with service manual).
Reconnect the battery.
