Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts; typically found between the engine block and the chassis.
3. Using a socket set, remove the bolts securing the engine mounts.
4. Inspect the mounts for cracks or signs of wear. If damaged, replace with new mounts.
5. Install the new mounts and torque the bolts to the manufacturer's specifications (usually around 50 Nm).

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission pan and drain the old fluid using a wrench to remove the drain plug.
2. Allow the fluid to completely drain and replace the drain plug.
3. Remove the transmission filter and replace it with a new one.
4. Refill the transmission with new fluid (use the manufacturer-recommended fluid type) through the dipstick tube, ensuring it reaches the correct level.
5. Start the engine and allow it to idle, then check the fluid level again and adjust as necessary.

4. Inspect and Balance Driveshaft

Sub-steps:
1. Inspect the driveshaft and universal joints for any signs of wear or play.
2. If there is any play or imbalance, remove the driveshaft by unbolting it from the transmission and rear differential.
3. Balance the driveshaft or replace it if it's damaged.
4. Reinstall the driveshaft and torque the bolts to the manufacturer's specifications.
