Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Lift the vehicle using a hydraulic jack and securely place jack stands under the frame.
Wear safety goggles and gloves.

2. Inspect and Test U-joints

Visual Inspection:
- Check the U-joints for any visible signs of wear, such as cracks or rust.
- Look for grease leakage, indicating a failed seal.
Play Check:
- Grasp the driveshaft and try to move it up, down, and side to side. Any significant movement indicates wear.
Noise Check:
- Rotate the driveshaft slowly and listen for any grinding or clunking sounds which indicate internal damage.

3. Replace U-joints (if necessary)

Tools Required: Socket set, U-joint puller, grease gun, torque wrench.
Steps:
1. Remove the driveshaft from the vehicle by unbolting the U-joint caps.
2. Use a U-joint puller to remove the old U-joint from the driveshaft and axle.
3. Clean the mating surfaces and apply grease to the new U-joint.
4. Install the new U-joint by reversing the removal steps, ensuring it is properly seated.
5. Reattach the driveshaft and torque the bolts to the manufacturer’s specifications.
