Why is my Ford Explorer 2020 making a clunking noise when turning?

Problem: Clunking Noise When Turning in a 2020 Ford Explorer

Potential Causes:

1. Worn or Damaged CV Joints
2. Loose or Damaged Suspension Components
3. Faulty Wheel Bearings
4. Power Steering Issues
5. Tire Issues (improper pressure or wear)

Tools Required:

• Jack and jack stands
• Socket set
• Torque wrench
• Pry bar
• Stethoscope or mechanic’s stethoscope
• Flashlight
• Wheel chocks

Step 1: Safety First

1. Park the vehicle on a level surface and engage the parking brake.
2. Place wheel chocks behind the rear wheels to prevent movement.

Step 2: Visual Inspection

1. Inspect the CV Joints:

   • Look for torn CV boots or grease leakage.
   • Check for signs of play in the joint when the wheel is turned.

2. Check Suspension Components:

   • Inspect control arms, bushings, and struts for wear or damage.
   • Look for any loose bolts or connections.

3. Examine Wheel Bearings:

   • With the wheel off, check for any play in the wheel hub.
   • Listen for grinding noises when spinning the wheel by hand.

4. Tire Condition:

   • Inspect tires for uneven wear patterns or low pressure.
   • Ensure all lug nuts are properly torqued to specification.

Step 3: Road Test

1. Drive the vehicle in a safe area and replicate the issue.
2. Note the conditions when the noise occurs (e.g., left turn, right turn, etc.).
3. If possible, have a passenger listen for the noise while you drive.

Repair Instructions

Step 4: Repair Based on Findings

A. If CV Joints are Worn:

1. Remove Wheel:

   • Loosen lug nuts, then lift vehicle using a jack and secure with jack stands.
   • Remove the wheel.

2. Remove Axle:

   • Disconnect the lower control arm and tie rod end if necessary.
   • Remove the axle nut and gently pull the axle out of the hub.

3. Replace CV Joint:

   • Remove the old CV joint and replace it with a new one.
   • Reassemble in reverse order ensuring all bolts are torqued to specification.

B. If Suspension Components are Loose/Damaged:

1. Tighten or Replace:

   • Tighten any loose bolts to factory specifications.
   • Replace any damaged components.

2. Reassemble:

   • Reinstall any components that were removed for access.

C. If Wheel Bearings are Faulty:

1. Remove Hub Assembly:

   • Remove the wheel and brake caliper.
   • Remove the hub assembly from the spindle.

2. Replace Bearings:

   • Press out the old bearings and press in new ones.
   • Reassemble the hub and ensure all components are torqued correctly.

D. If Power Steering Issues are Suspected:

1. Check Fluid Level:

   • Inspect the power steering fluid level and top off if low.

2. Inspect for Leaks:

   • Look for leaks in the power steering hoses and pump.
   • Replace any faulty components.

E. If Tire Issues are Present:

1. Adjust Tire Pressure:

   • Inflate tires to the manufacturer’s recommended pressure.

2. Rotate or Replace Tires:

   • Rotate tires according to the service schedule or replace if significantly worn.

Conclusion

After completing the repairs, take the vehicle for a test drive to ensure the clunking noise has been resolved. If the noise persists after all checks and repairs, consider seeking further diagnostic assistance from a professional technician, as the issue may be more complex or require specialized tools.
