Solution
1. Preparation
  • Tools Required:
    • Jack and jack stands
    • Socket set
    • Torque wrench
    • Drain pan
    • Differential fluid
    • Gasket maker or new gasket
  • Safety Warnings: Ensure the vehicle is securely supported on jack stands before working underneath.
2. Drain and Remove Differential Cover
  1. Place a drain pan under the differential.
  2. Remove the bolts securing the differential cover using a socket set.
  3. Carefully pry off the differential cover, allowing fluid to drain completely.
3. Inspect Internal Components
  1. Visual Inspection: Check the condition of the gears, bearings, and shims for any signs of wear, chips, or discoloration.
  2. Check Bearing Play: Rotate the pinion and check for excessive play in the bearings; replace if necessary.
4. Replace Differential Fluid
  1. Clean the differential cover and mating surfaces thoroughly.
  2. Apply a new gasket or gasket maker as needed.
  3. Reinstall the differential cover and torque the bolts to the manufacturer's specifications (typically around 30-35 ft-lbs, but verify with service manual).
  4. Fill the differential with the recommended fluid type (typically SAE 75W-140 or as specified by manufacturer) until the fluid level reaches the fill hole.
5. Reassemble and Test
  1. Reinstall any components removed during diagnosis.
  2. Test drive the vehicle to ensure the noise has been resolved.
