Problem Statement

Learn how to diagnose and fix suspension noise in Ford Explorer Sixth Generation (2020-present). Step-by-step guide with symptoms and solutions.

Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the vehicle to cool before starting any work to prevent burns.

Symptoms

•Clunking or knocking noise when driving over bumps
•Creaking sounds during turns or when weight shifts
•Excessive vibration felt through the steering wheel
•Dipping or sagging of the vehicle during acceleration or braking
•Uneven tire wear on front or rear tires

Diagnostic Steps

1
Inspect the suspension components (struts, shocks, control arms) for any visible signs of damage or wear.
2
Ensure all suspension-related bolts and hardware are tight and secure.
3
Perform a bounce test by pushing down on each corner of the vehicle; observe if it returns smoothly or bounces excessively.
4
Have an assistant drive the vehicle slowly over bumps while you listen from outside for abnormal noises.
5
Examine rubber bushings and ball joints for cracks, tears, or excessive wear.
6
Conduct a test drive to replicate the noise under different conditions (turning, accelerating, braking).

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
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Socket set
•Torque wrench
•Jack and jack stands
•Pry bar
•Chassis ear (optional)

Parts Required

•Shock absorbers/struts (if necessary)
•Control arms (if necessary)
•Bushings or ball joints (if necessary)

Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, pry bar, chassis ear (optional).
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery if working on electronic suspension components.

2. Inspect and Replace Worn Components

Inspect Suspension Components:
- Use a pry bar to check for play in control arms, ball joints, and bushings.
- Replace any worn or damaged parts.
Replace Shock Absorbers/Struts:
- If shocks or struts are leaking or not functioning correctly, remove and replace them.
- Use a torque wrench to install with manufacturer-specified torque values.

3. Tighten Loose Hardware

Inspect and tighten all bolts and nuts related to the suspension system.
Use a torque wrench to ensure proper specifications are met.

4. Reassemble and Test

Reassemble any components that were removed during inspection.
Reconnect the battery.
Lower the vehicle and perform another bounce test to ensure proper function.
