Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, jack and jack stands, socket set, torque wrench, and a visual inspection mirror.
Ensure the vehicle is parked on a level surface with the engine off.

2. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressures using a tire pressure gauge and adjust to manufacturer specifications.
2. Inspect tires for uneven wear patterns; if found, consider rotating or replacing tires.
3. If vibration persists, proceed to wheel alignment and balancing.

3. Engine and Transmission Mounts Inspection

Sub-steps:
1. Visually inspect engine and transmission mounts for cracks or separations.
2. If damage is noted, remove the old mount using a socket set.
3. Install new mounts, ensuring they are torqued to manufacturer specifications.

4. Driveshaft and CV Joints Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the driveshaft for any signs of bending or damage.
3. Check CV joints for grease leakage or torn boots; replace if necessary.

5. Spark Plugs and Ignition Coils Check

Sub-steps:
1. Remove spark plugs using a socket set.
2. Inspect for wear or carbon buildup; replace if necessary.
3. Check ignition coils for proper functioning; replace if found defective.
