Differential Fluid Inspection and Replacement

Differential Fluid Inspection and Replacement
1. With the vehicle on level ground, inspect the differential fluid with the ignition switch turned to LOCK (0).





2. Remove the oil filler plug (A) and the sealing washer (B), then check the condition of the fluid, and make sure the fluid is at the proper level (C).
3. The fluid level must be up to the fill hole. If it is below the hole, add the recommended fluid until it runs out, then reinstall the oil filler plug with a new sealing washer.





4. If the fluid is dirty, remove the drain plug (D), and drain the fluid.
5. Clean the drain plug, then reinstall it with a new sealing washer, and refill the differential with the recommended fluid to the proper level.
