★ Top Answer
The 2003 Ford Explorer uses A75W-140 differential fluid, which lubricates the axle and is designed to handle high pressure situations. Unlike engine oil, which is tailored for high-temperature engine conditions, this gear oil is thicker and helps prevent excessive friction in the axle. Keeping this fluid at the proper level is crucial to avoid rapid wear and potential damage. It is suggested to replace this fluid every 30,000 to 60,000 miles, which means you may only need to do this a few times during the car's lifespan.
