Solution

1. Preparation

Gather tools and parts needed for the check and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Lift the Vehicle

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

3. Remove the Driveshaft (if necessary)

Use a socket set to remove the bolts securing the driveshaft to the differential and transmission.
Carefully slide the driveshaft out and set it aside.

4. Inspect the U-Joint

Check for any visible damage such as rust, cracks, or excessive wear.
Manually rotate the U-joint while observing for smooth movement; feel for any binding or roughness.

5. Greasing the U-Joint

If equipped with grease fittings, use a grease gun to apply grease until it oozes out of the seals.
Wipe away any excess grease.

6. Reinstall Driveshaft

Align the driveshaft with the yoke, ensuring it is properly oriented.
Reattach the driveshaft using the original bolts and torque them to the manufacturer’s specifications (usually between 15-25 ft-lbs).

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
