3. Replace the drain plug and refill with new transmission fluid as per manufacturer specifications.
4. For engine oil, drain and replace with the recommended oil and filter.

3. Check and Replace U-joints (if necessary)

Tools Required: U-joint puller, socket set
Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the driveshaft from the vehicle by loosening the bolts at the U-joints.
3. Use a U-joint puller to remove the old U-joints and install new ones.
4. Reinstall the driveshaft, ensuring bolts are torqued to manufacturer specifications.

4. Inspect and Replace Engine Mounts (if necessary)

Tools Required: Socket set, jack
Sub-steps:
1. Raise the vehicle and support it with jack stands.
2. Locate the engine mounts and inspect for cracks or wear.
3. Remove the bolts securing the mounts and carefully lift the engine using a jack as necessary.
4. Install the new engine mounts and torque bolts to the specified values.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Monitor for any check engine lights and test drive to ensure shuddering has been resolved.
