Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, jack and jack stands.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine and transmission mounts.
3. Inspect mounts for any visible cracks, separation, or excessive wear.
4. Remove the bolts securing the faulty mount using a socket set.
5. Replace with new mounts (ensure they meet OEM specifications) and torque the bolts to manufacturer specifications.

3. Check and Top Off Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or plug and check fluid level; add fluid if necessary.
3. If the fluid is dirty or burnt, consider a transmission fluid change (flush and replace with the manufacturer-recommended fluid).

4. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the ignition coils using a socket set.
4. Replace spark plugs, ensuring the gap is set to manufacturer specifications.
5. Reinstall ignition coils and reconnect electrical connectors.

5. Inspect Driveshaft and CV Joints

Sub-steps:
1. Visually inspect the driveshaft for any dents or bends.
2. Check CV joints for torn boots or leaks.
3. Replace any damaged components as necessary, ensuring proper torque when reinstalling.
