Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Remove any cladding or components obstructing access to the engine mounts.
Visually inspect the engine mounts for cracks or excessive wear.
If damaged, remove the bolts securing the engine mounts and replace them with new mounts. Torque bolts to manufacturer specifications.

3. Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench, dielectric grease
Remove the ignition coil covers if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using the spark plug socket.
Install new spark plugs, applying dielectric grease to the coil boots before reinstalling the coils. Torque spark plugs to manufacturer specifications.

4. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel, catch pan
With the engine running, check the transmission fluid level using the dipstick.
If fluid is low or burnt, drain the transmission and replace it with the recommended fluid type. Fill to the appropriate level as indicated in the owner's manual.

5. Inspect Drive Shafts and CV Joints

Tools Required: Jack, jack stands, socket set
Raise the vehicle using a jack and secure it with jack stands.
Inspect the drive shafts for any visible damage or excessive play.
Remove and replace any damaged CV joints or drive shafts as necessary, ensuring proper torque on all fasteners.
