Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, OBD-II scanner, stethoscope (for noise diagnosis).
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery before working on electrical systems.

2. Inspect and Replace Engine Mounts (if required)

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically found at the front, rear, and sides of the engine).
3. Inspect each mount for cracks, separation, or excessive wear.
4. If any mounts are damaged, remove the bolts securing the engine mount to the frame and engine.
5. Replace with new mounts and torque to the manufacturer’s specifications (usually found in the service manual).

3. Examine Suspension Components (if required)

Sub-steps:
1. Inspect the struts and shocks for any oil leakage or physical damage.
2. Check control arms and bushings for wear and tear or any play.
3. Tighten any loose bolts and replace worn parts as necessary.
4. Torque all bolts to manufacturer specifications.

4. Check Engine Oil (if required)

Sub-steps:
1. Remove the dipstick and check the oil level; add oil if low.
2. Check the oil condition for contamination or sludge.
3. If oil is dirty or has not been changed per the maintenance schedule, perform an oil change.
4. Replace oil filter and refill with the recommended oil type and quantity.
