What axle ratio was available for 2002 model year Ford Expedition?

The 2002 Ford Expedition offered several axle ratios depending on the engine and drivetrain configuration. There wasn't one single ratio. You'd typically find either a 3.73 or a 4.10 axle ratio. The 4.10 ratio was more common with heavier-duty configurations or those with the larger engine. However, to know for certain the ratio in a *specific* 2002 Expedition, you'd need to check the vehicle's specifications or the sticker in the driver's side door jamb.
