Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, fluid catch pan
Sub-steps:
1. Remove the transmission fluid pan using a socket set.
2. Allow the old fluid to drain completely into the catch pan.
3. Inspect the fluid for metal shavings or burnt smell.
4. Replace the filter if necessary.
5. Reinstall the pan with a new gasket and torque to manufacturer specifications.
6. Refill with the recommended transmission fluid through the dipstick tube using a funnel.

3. Inspect and Replace Engine Mounts

Tools Required: Jack and jack stands, socket set
Sub-steps:
1. Safely lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts and visually inspect for cracks or excessive wear.
3. If damaged, remove the bolts securing the engine mount to the engine and frame.
4. Install the new engine mounts and torque bolts according to specifications.

4. Inspect Drive Shafts and CV Joints

Tools Required: Jack and jack stands, socket set
Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Visually inspect the drive shafts and CV joints for cracks or leaks.
3. If any issues are found, replace the affected components using the socket set to remove and install new parts.

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

Tools Required: Socket set, spark plug socket
Sub-steps:
1. Remove the ignition coils by unscrewing them from the engine.
2. Extract the old spark plugs using a spark plug socket.
3. Install new spark plugs and tighten to the recommended torque.
4. Reattach the ignition coils securely.
