Solution

1. Preparation

Tools required: Floor jack, jack stands, socket set, ratchet, torque wrench, differential fluid pump, drain pan.
Lift the rear of the vehicle using a floor jack and secure it on jack stands.
Ensure the vehicle is on a flat surface and the engine is off.

2. Inspect and Replace Differential Fluid

Sub-steps:
1. Locate the differential cover and clean around the bolts to prevent contamination.
2. Remove the differential cover bolts using a socket set.
3. Carefully pry off the cover to drain the old fluid into a drain pan.
4. Inspect the old fluid for metal shavings or debris, indicating wear.
5. Clean the differential cover and the mating surface.
6. Refill with new differential fluid using a pump, adhering to the manufacturer’s specifications (typically SAE 75W-140 for Mustangs).
7. Reinstall the cover with a new gasket or sealant and torque the bolts to the specifications provided in the service manual.

3. Inspect and Replace Bearings or Gears (if necessary)

Sub-steps:
1. If noise persists after fluid change, the differential may need disassembly.
2. Remove the driveshaft by unbolting it from the differential.
3. Remove the differential cover again to access the gears and bearings.
4. Inspect the ring and pinion gears for wear or pitting.
5. Check bearings for play or damage and replace if necessary.
6. Reassemble the differential, ensuring proper alignment and torque specifications are followed.
