Disconnect the battery to ensure safety while performing repairs.

2. Inspect and Replace Engine and Transmission Mounts

Raise the vehicle and securely support it with jack stands.
Locate the engine and transmission mounts.
Inspect each mount for cracks, excessive wear, or separation.
If any mounts are damaged, remove the bolts using a socket set.
Install new mounts, ensuring they are properly aligned.
Torque the bolts to the manufacturer's specifications.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Remove the engine cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils using a socket set.
Replace spark plugs using a spark plug socket.
Reinstall the ignition coils and reconnect the electrical connectors.

4. Inspect and Replace Driveshaft or CV Joint (if necessary)

Remove the front wheels for better access.
Check the driveshaft and CV joints for excessive play or damage.
If necessary, remove the driveshaft by unbolting it from the transmission and suspension components.
Replace any damaged components with new ones, following the manufacturer’s specifications for installation.

5. Check and Adjust Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the manufacturer's recommended pressure.
Inspect for uneven tire wear; if found, consider a wheel alignment.
