Solution

1. Preparation

Park the vehicle on a flat surface and set the parking brake.
Disconnect the negative terminal of the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Engine/Transmission Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine and transmission mounts using a socket set.
Use a pry bar to gently lift the engine or transmission to relieve pressure on the mounts.
Inspect the mounts for cracks or deterioration; replace if necessary.
Reinstall the new or repaired mounts and torque to manufacturer's specifications.

3. Check and Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, ratchet, torque wrench
Remove the ignition coils by unscrewing the bolts or clips securing them.
Remove the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace if they show signs of fouling or damage.
Install new spark plugs with the correct gap and torque to specifications.
Reinstall the ignition coils.

4. Inspect and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, wrench set
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Use a fuel line disconnect tool to disconnect the fuel lines from the filter.
Remove the fuel filter from its bracket and install the new filter in the same orientation.
Reconnect the fuel lines and reinstall the fuel pump relay.

5. Inspect CV Joints and Drive Shafts

Tools Required: Jack and jack stands, socket set
Lift the vehicle and secure it on jack stands.
Inspect the CV joints and drive shafts for signs of damage or excessive play.
If any components are damaged, replace the affected CV joint or drive shaft.
