Solution

1. Preparation

Gather tools: socket set, torque wrench, OBD-II scanner, jack stands, and a multimeter.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Engine and Transmission Mounts

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Locate the engine and transmission mounts.
3. Visually inspect mounts for cracks or excessive wear.
4. Use a pry bar to check for movement in the mounts; replace any that are damaged.

3. Check Serpentine Belt and Pulleys

Sub-steps:
1. Remove the engine cover if necessary to access the serpentine belt.
2. Inspect the belt for cracks, fraying, or glazing.
3. Check the pulleys for misalignment or play. Replace the belt and/or pulleys if needed.

4. Inspect CV Joints and Axles

Sub-steps:
1. Remove the front wheels for better access to the CV joints and axles.
2. Inspect the outer and inner CV boots for tears or leaking grease.
3. Check for play in the CV joints by moving the axle back and forth; replace if worn.

5. Inspect for Engine Misfires

Sub-steps:
1. Reconnect the battery and start the engine.
2. Use the OBD-II scanner to check for misfire-related codes.
3. If misfires are detected, inspect spark plugs and ignition coils; replace any faulty components.
