2000 Ford Windstar 3.8 engine 157,000 mi. I have a loud steady humming coming from the front end, directly related to speed of vehicle. It is getting louder.Could it be tire related or knuckle related? They are Douglas tires and 1 yr. old.

Try just visually inspecting tires for odd wear that can make sounds and rotate them to see if noise follows the wheels/tires or stays. If it stays I would suspect wheel bearing is failing. Those frequently get louder on turns at some speed one way more than the other. So called knuckles or other front end parts aren't really turning/spinning with the speed of the vehicle so probably not.

Concentrate on what is turning that is fixed to vehicle speed. Bearings getting louder over little time can fail quickly so do rule those in or out of the noise issue.

Any noise is a warning of something not right and hard to pin down just what without being there to hear or feel it,

Thank you, Tom for your response. I had the tires rotated and still have the noise. That leads me to believe it's the wheel bearings.

OK - If noise didn't change or move than wheel bearing is high on the list. Never say always but most when failing will change volume of noise with shift of weight as in steering around a corner at some speed. If early (doubt it by description) may be difficult to peg which just spinning wheels while hoisted by hand.

Frequently takes some weight and speed. If serious it would have freeplay which is plain dangerous now there's no time to waste. Still some other reasons for this noise. Humming or sounding like you have a knobby tire on one wheel is the common feel or sound. Some noises can be a splash shield touching rotor but more of a scraping sound.

Worn brakes are on the maybe list too. IDK - sometimes you need a driver and listen from passenger's side to get a better sense of where it is from.

Just don't ignore noises like this,
