Common Causes of Rear Differential Noise in Ford Explorer 2020

The rear differential noise in a 2020 Ford Explorer can stem from several issues. Understanding the symptoms, diagnosing the problem, and performing the necessary repairs will help resolve this issue. Below are the common causes, diagnostic steps, required tools, and repair instructions.

Tools Required
  1. Jack and Jack Stands: To safely lift the vehicle.
  2. Socket Set: For removing differential cover and other components.
  3. Torque Wrench: For proper reassembly.
  4. Fluid Pump: For adding differential fluid.
  5. Magnet or Pick-Up Tool: To check for metal shavings in the fluid.
  6. Differential Fluid: Ensure you have the correct type specified in the owner’s manual (usually a synthetic 75W-140).
  7. Safety Glasses and Gloves: For personal protection.
Repair Instructions

1. Replace Differential Fluid

  • Drain the Fluid:
    • Lift the vehicle and secure it on jack stands.
    • Place a drain pan under the differential, remove the drain plug, and allow the fluid to completely drain.
  • Inspect for Debris:
    • Use a magnet to check for metal shavings in the fluid.
  • Replace with New Fluid:
    • Reinstall the drain plug.
    • Use a fluid pump to refill the differential with new fluid until it reaches the fill level.

2. Replace Differential Bearings (if necessary)

  • Remove Axles:
    • Unbolt the axle shafts from the differential.
    • Carefully slide the axles out of the differential.
  • Remove Differential Cover:
    • Remove the bolts securing the differential cover and carefully pry it off.
  • Inspect Gears and Bearings:
    • Look for signs of wear on the ring and pinion gears.
    • Check the condition of the carrier and pinion bearings.
  • Replace Damaged Bearings:
    • If bearings are damaged, they will need to be pressed out and new ones pressed in, which requires a bearing press.
  • Reassemble:
    • Reinstall the differential cover with a new gasket and torque the bolts to manufacturer specifications.
    • Reinstall the axles, ensuring they are properly seated.

3. Inspect or Replace the Differential Assembly (if severe)

  • If significant damage to the gears is found, it may be necessary to replace the entire differential assembly, which involves detailed disassembly and reassembly.
Conclusion

By following the diagnostic steps and repair instructions outlined above, you can effectively identify and resolve rear differential noise in the 2020 Ford Explorer. If the issue persists after performing these repairs, it may be beneficial to consult a professional technician for further diagnosis.
