Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine and Transmission Mounts

Tools Required: Socket set, torque wrench.
Remove any components obstructing access to the engine and transmission mounts.
Visually inspect the mounts for cracks, tears, or degradation.
Replace any damaged mounts with new ones, ensuring they are torqued to manufacturer specifications.

3. Check and Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench.
Remove the ignition coils and spark plugs.
Inspect spark plugs for wear; replace them if they show signs of fouling.
Replace ignition coils if any are found defective.
Reinstall spark plugs and coils, ensuring a proper torque is applied based on specifications.

4. Transmission Fluid Inspection and Change

Tools Required: Transmission fluid pump, fluid catch pan, socket set.
Check the transmission fluid level using the dipstick.
If low, add the recommended transmission fluid type.
If fluid is burnt or contaminated, drain the transmission fluid and replace it with new fluid.

5. Inspect Drive Shaft and CV Joints

Tools Required: Jack and jack stands, socket set.
Lift the vehicle safely and inspect the drive shaft for any visible damage or excessive play.
Check CV joints for signs of wear and tear.
