Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with jack stands.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Driveshaft

Sub-steps:
1. Locate the bolts securing the driveshaft to the U-joint.
2. Use a socket wrench to remove the bolts (typically 10mm or 12mm).
3. Carefully slide the driveshaft out of the U-joint, noting the orientation for reinstallation.

3. Replace U-joint

Sub-steps:
1. Use a U-joint puller or hammer to remove the old U-joint from the driveshaft.
2. Clean the U-joint socket on the driveshaft with a wire brush.
3. Apply grease to the new U-joint and install it by pressing it into the driveshaft socket using the U-joint puller.
4. Ensure the U-joint is seated properly and rotates freely.

4. Reinstall Driveshaft

Sub-steps:
1. Align the driveshaft back into the U-joint, ensuring it matches the original orientation.
2. Reinstall the bolts and tighten them to the manufacturer's torque specification (usually around 15-20 ft-lbs).
3. Reconnect the battery.

5. Final Inspection

Sub-steps:
1. Lower the vehicle from jack stands.
2. Perform a visual inspection to ensure everything is properly secured.
3. Test drive the vehicle to verify that the vibration issue has been resolved.
