Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Tighten Engine Components

Sub-steps:
1. Use a socket set to check and tighten all bolts and nuts on the engine mounts and brackets.
2. If the mounts are damaged, replace them with OEM parts.

3. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the oil to drain into a suitable container.
2. Replace the oil filter using an oil filter wrench.
3. Reinstall the oil drain plug with a torque value of 30 ft-lbs (40 Nm).
4. Fill the engine with the recommended oil type (e.g., 0W-20) using a funnel, ensuring the correct level is reached on the dipstick.

4. Inspect and Repair Suspension Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Visually inspect the struts, shocks, and control arms for any signs of wear or damage.
3. Replace any worn components using appropriate torque specifications for bolts.

5. Inspect Exhaust System

Sub-steps:
1. Visually check for loose or damaged exhaust hangers and brackets.
2. Tighten or replace any loose components to eliminate potential knocking sounds.
