Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, multimeter.
Ensure vehicle is on a flat surface and securely elevated.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Engine and Transmission Mounts

Sub-steps:
1. Locate the engine and transmission mounts in the engine bay.
2. Visually inspect for cracks, tears, or excessive wear.
3. If damaged, remove bolts securing the mounts using a socket set.
4. Replace with new mounts, ensuring proper alignment.
5. Torque bolts to the manufacturer’s specifications (typically found in the service manual).

3. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coil connectors.
3. Remove the ignition coils using a socket set.
4. Replace old spark plugs with new ones, ensuring they are gapped correctly.
5. Reinstall ignition coils and reconnect connectors, ensuring they click into place.

4. Inspect and Replace Driveshaft or CV Joints

Sub-steps:
1. Raise the vehicle and secure on jack stands.
2. Inspect the driveshaft for any visible damage or play.
3. Check CV joints for torn boots or excessive movement.
4. If damaged, remove the driveshaft or CV joint using a socket set.
5. Replace with new components, ensuring all bolts are torqued to specifications.

5. Check and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the pressure in all tires.
2. Inflate or deflate tires to the manufacturer’s recommended pressure (found on the driver’s door jamb).
3. Inspect for uneven wear or damage; replace tires if necessary.
