Problem Statement

Learn how to diagnose and fix knocking sounds in Ford Explorer Fifth Generation (2011-2019). Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components
•Allow engine to cool before performing oil changes or inspection

Symptoms

•Knocking or tapping noise coming from the engine or suspension area
•Noise changes with engine RPM (increases with acceleration)
•Possible vibration felt through the steering wheel or floorboards
•Loss of power during acceleration
•Check engine light illuminated (if applicable to the underlying issue)

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any stored diagnostic trouble codes (DTCs)
2
Inspect the engine bay visually for loose components, damaged parts, or oil leaks that may contribute to the noise
3
Check the oil level and quality to ensure proper lubrication; low oil could lead to knocking sounds
4
Perform a listen test with a mechanic’s stethoscope to pinpoint the origin of the knocking sound (engine, transmission, or suspension)
5
Inspect the suspension components for wear or damage, including bushings, struts, and control arms
6
Examine the drive belt and pulleys for wear or misalignment that may cause knocking

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights

Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, mechanic’s stethoscope, socket set, torque wrench, and safety glasses.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Address Engine Noise

Check and change engine oil:
- Remove the oil drain plug using a socket set and drain old oil into a suitable container.
- Replace the oil filter using an oil filter wrench. Ensure the new filter is properly installed and filled with oil.
- Reinstall the drain plug and refill engine with the recommended oil type (check owner’s manual for specifications).
- Torque the drain plug to the manufacturer’s specifications.
Inspect and replace damaged components:
- If engine mounts are worn, replace them. Remove bolts securing the engine mount using a socket set, replace with new mounts, and torque to specifications.
- Replace any damaged belts or pulleys identified in the diagnostic steps.

3. Address Suspension Noise

Inspect and replace suspension components:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access the suspension components.
- Inspect control arms, bushings, and struts for wear or damage. Replace any components as necessary.
- Ensure all bolts are torqued to the manufacturer's specifications upon reassembly.
