Disconnect the battery to ensure safety while working.

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; visually inspect for cracks or excessive wear.
3. Use a socket set to remove the bolts securing the mounts.
4. Replace damaged mounts with new OEM or quality aftermarket mounts.
5. Torque the bolts to the manufacturer’s specifications (refer to repair manual for exact torque values).

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors and remove the coils.
3. Use a spark plug socket to remove old spark plugs from the cylinder head.
4. Inspect the old plugs for wear and replace them if necessary with new ones (ensure correct gap).
5. Reinstall the spark plugs and ignition coils, ensuring they are secured properly.

4. Inspect and Balance Tires

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Inspect tires for uneven wear or damage and replace if necessary.
3. Take tires to a shop for balancing or use a wheel balancer if available.
4. Reinstall balanced wheels and torque lug nuts to manufacturer specifications.
