^^^ It's a Ford Chassis? If so, there's a Vehicle Speed Sensor (VSS) on the front top of the differential. Held down by a 10mm capscrew, sealed with an O-ring. Clean the area, pull the VSS, and pour your new lube down the VSS hole using a small funnel. Do this with the magnetic fluid level plug removed. Stop when the new fluid reaches the level plug hole.
