Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Multimeter
Jack and jack stands

2. Inspect and Replace Engine and Transmission Mounts

Sub-steps:
1. Use the jack to support the engine slightly.
2. Remove the bolts securing the engine mounts using the socket set.
3. Lift the engine gently to remove any tension from the mounts.
4. Replace with new engine mounts, ensuring proper alignment.
5. Torque the bolts to manufacturer specifications (typically around 30-40 Nm).

3. Check and Replace Driveshaft and Universal Joints

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
2. Remove the driveshaft by unscrewing the bolts at the differential and transmission ends.
3. Replace worn or damaged universal joints.
4. Reinstall the driveshaft and torque the bolts to specifications (usually 60-70 Nm).

4. Test and Replace Ignition Components

Sub-steps:
1. Remove the spark plugs using the socket set and inspect for wear.
2. Replace spark plugs if worn, ensuring they are gapped correctly (typically around 0.8 mm).
3. Check the ignition coils for proper voltage using a multimeter; replace if faulty.
