Chasing bearing noise
Guys, I have a 2007 f150. I'm chasing a bearing noise. It becomes evident around 30mph. It's very hard to tell if it's coming from front or rear of vehicle. If you go over a decline in the road quickly to unload the weight of the truck from the wheels it goes away for that split second. A slight and I do mean slight turn to the right makes the noise go away. Turn left noise remains but doesn't seem to get louder. It's a electronic 4x4. Noise is same in 2wd and 4wd. Have replaced right front bearing and rear axle bearings and seals. Also rotated tires. Noise is still there. Any insight is appreciated!

I recently bought a 2010 Escape that I thought had a bad bearing. I couldn't tell if it was from the front or rear. I changed the tires and the noise was gone.
Maybe a tire is out of round. Try lifting a wheel slightly and spin the wheel by hand to see if the gap to ground is constant.

I had replaced both of my front wheel bearings (and the rotor at the same time). Fairly expensive at nearly $90.00 apiece, but what ya gonna do...??? My truck needed them both replaced at approx 95K miles. (but my truck is 2wd)
Have you tried to discern if it makes a noticeable difference in noise if you're turning left or right? Try jacking up the front and spin them by hand also can give ya an idea.

It seems since you replaced one bearing on the front the other one is failing also. My money would be replacing now the left front bearing.
