Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent any electrical issues while working.
Ensure the vehicle is on a flat surface and securely lift it using jack stands if necessary.

2. Inspect and Replace Engine Mounts

Sub-steps:
- Locate the engine mounts and visually inspect them for cracks or signs of failure.
- Use a socket set to remove the bolts securing the damaged engine mounts.
- Replace the damaged mounts with new ones, ensuring proper alignment.
- Torque the bolts to the manufacturer’s specifications (consult the service manual for specific torque values).

3. Check and Replace Transmission Fluid

Sub-steps:
- Locate the transmission dipstick and remove it to check the fluid level.
- If low, drain the old fluid using a fluid pump and replace it with the manufacturer-recommended transmission fluid.
- Refill to the proper level and check for leaks.

4. Inspect and Replace Spark Plugs and Ignition Coils

Sub-steps:
- Remove the engine cover if necessary to access the spark plugs.
- Disconnect the ignition coil connectors and remove the coils using a socket set.
- Replace old spark plugs with new ones, ensuring they are gapped correctly.
- Reinstall the ignition coils and reconnect the electrical connectors.

5. Inspect Drive Shafts and CV Joints

Sub-steps:
- Lift the vehicle and remove the wheels for better access.
- Inspect the drive shafts and CV joints for any signs of wear, such as torn boots or excessive play.
- Replace any damaged components with new parts.
