Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Locate the engine mounts and visually inspect for cracks or excessive play.
3. Use a socket set to remove the bolts securing the damaged engine mounts.
4. Replace with new engine mounts, ensuring they are torqued to manufacturer specifications (usually around 30 Nm).

3. Check and Change Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or drain plug.
2. Remove the dipstick or drain plug and check the fluid level; add fluid if necessary.
3. If the fluid is burnt or contaminated, drain the transmission fluid completely.
4. Replace with new, manufacturer-approved transmission fluid and refill to the correct level.

4. Inspect Driveshaft and CV Joints

Sub-steps:
1. Inspect the driveshaft for any visible damage or looseness.
2. Check CV joints for signs of cracking or boot damage.
3. If damage is found, replace the driveshaft or CV joint as necessary, using a torque wrench to tighten bolts to manufacturer specifications.

5. Inspect and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover to access the spark plugs.
2. Use a socket set to remove the spark plugs, inspecting them for wear or fouling.
3. Replace with new spark plugs, ensuring they are gapped correctly.
4. Test and replace any faulty ignition coils if necessary.
