EXCESSIVE NOISE COMING FROM TIRES/WHEELS.

2002 Ford Explorer • 143,000 miles

I've had it aligned and tire wear is normal. Sounds like an airplane. Maybe wheel bearings worn out?

Are the tires cupping? Run your hand over
Them. Do thay feel choppy. If yes you might need shocks or wheel balance

An "airplane engine" is exactly how I describe noisy wheel bearings. If the noise changes when you steer to one side, such as when changing lanes at highway speed, it's definitely a wheel bearing. If the noise doesn't change, it still can be a wheel bearing.

The best way I've found to identify which bearing is noisy is to run the vehicle on a hoist and listen next to each one with a stethoscope.
