Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if working on the engine.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Disconnect the ignition coils from the spark plugs.
Use a socket wrench to remove the spark plugs.
Inspect the spark plugs for wear; replace any that are damaged or worn.
Gap the new spark plugs according to manufacturer specifications before installation.
Install the new spark plugs and reconnect the ignition coils.

3. Check Engine Mounts

Use a jack to lift the engine slightly if needed for access.
Visually inspect the engine mounts for cracks or signs of deterioration.
Replace any damaged engine mounts with new ones, ensuring to torque the bolts to manufacturer specifications.

4. Transmission Fluid Inspection

Locate the transmission dipstick; remove it and check the fluid level.
If low, add the appropriate transmission fluid as per the manufacturer's specifications.
If the fluid is discolored, consider a transmission fluid change.

5. Inspect Driveshaft and CV Joints

Raise the vehicle securely on jack stands.
Inspect the driveshaft for any signs of damage or imbalance.
Examine CV joints for any tears in the rubber boots or signs of grease leaking.
