Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, flashlight
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to avoid any electrical short circuits during inspection.

2. Check Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, top up with the manufacturer-recommended oil type. If dirty, proceed to an oil change.

3. Inspect Suspension Components

Safely raise the vehicle using a jack and secure with jack stands.
Visually inspect control arms, bushings, and struts for any signs of wear or damage.
Tighten any loose bolts to manufacturer specifications using a torque wrench.

4. Examine Drivetrain

Inspect the transmission and differential for any signs of leaks or unusual noises.
If necessary, drain and replace the transmission fluid with the appropriate type.
Check for any abnormal movement in the driveshaft or axles.

5. Inspect Exhaust System

Check for loose brackets or clamps that may be causing the knocking sound.
Tighten any loose components and replace any damaged parts as needed.

6. Replace Engine Mounts (if necessary)

If engine mounts are found to be damaged, remove the old mounts using a socket set.
Install new engine mounts and torque to manufacturer specifications.
