Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, jack stands, safety goggles, and gloves.
Safety Warnings: Disconnect the battery before starting any work on the vehicle’s electrical systems. Allow the engine to cool before inspecting fluid levels.

2. Transmission Fluid Inspection

Check the transmission fluid level using the dipstick located near the transmission.
If low, add the manufacturer-recommended transmission fluid type (typically Mercon LV for Ford vehicles) until it reaches the full mark.
If the fluid appears dark or has a burnt smell, consider a transmission fluid change.

3. Transmission Pan Inspection

Raise the vehicle securely using jack stands.
Place a fluid catch pan underneath the transmission.
Remove the transmission pan bolts and carefully lower the pan to inspect for metal shavings or debris.
Clean the pan and replace the transmission filter if needed.

4. Drivetrain Inspection

Inspect the driveshaft and CV joints for any signs of wear or damage.
Replace any worn or damaged components as necessary.
Ensure that all bolts and fasteners are properly torqued to manufacturer specifications.

5. Rear Differential Inspection

Inspect the rear differential fluid level by removing the fill plug.
Add manufacturer-recommended gear oil if low.
Listen for unusual noises while manually rotating the driveshaft, indicating possible issues with the differential.

6. Brake System Inspection

Remove the wheel to access the brake components.
Inspect brake pads for wear and ensure they are not dragging or damaged.
Replace any worn components as necessary and ensure the caliper is functioning properly.
