Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, engine compression tester, jack, and jack stands.
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is on a flat surface and properly secured with jack stands.

2. Address Engine Issues

Check Engine Oil:
- Remove the dipstick, wipe clean, and reinsert to check the level.

Inspect Engine Mounts:
- Visually inspect engine mounts for cracks or excessive wear.
- If damaged, remove the bolts securing the mount to the frame and engine using a socket set.
- Replace with new mounts and torque bolts to manufacturer specifications (consult service manual for torque values).

3. Inspect Suspension Components

Visual Inspection:
- Lift the vehicle using a jack and secure on jack stands.
- Check struts, bushings, and control arms for signs of wear or damage.
- Replace any worn components, ensuring they are torqued to specifications.
Test Drive:
- After repairs, lower the vehicle and take it for a test drive to ensure the knocking noise is resolved.
