Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Remove any components obstructing access to the engine mounts (e.g., air intake duct).
2. Use a jack to support the engine gently.
3. Remove the bolts securing the engine mounts to the engine and chassis.
4. Replace with new engine mounts.
5. Torque the bolts to the manufacturer's specifications (usually around 50-70 ft-lbs).

3. Transmission Fluid Change

Sub-steps:
1. Remove the transmission drain plug and drain the old fluid into a suitable container.
2. Replace the filter if applicable (check service manual for specifics).
3. Reinstall the drain plug and torque to specifications.
4. Refill the transmission with new fluid (use the manufacturer's recommended type, typically ATF).
5. Start the engine and let it idle, checking for leaks around the drain plug.

4. Inspect and Replace Driveshaft/CV Joints

Sub-steps:
1. Safely lift the vehicle using a jack and secure with jack stands.
2. Remove the wheel and tire assembly to access the CV joints.
3. Inspect the CV boots for tears and the joints for play.
4. If damaged, remove the CV joint assembly and replace it with a new one.
5. Reassemble components and ensure proper torque specifications are followed.
