Q: howling noise?

asked by on July 04, 2016

I have a howling noise (kinda like a high pitch hum) that sounds like its coming from the front of the truck, but it could be the back, not very good at pinpointing lol. i heard it could be wheel bearing, tires, or rearend. the thing is, it doesnt matter if im accelerating, breaking, or coasting, the noise will still happen, but only at certain speeds, like 25 mph, 45 mph, 60. and when it starts making the noise, the only way it quiets up is if i make a right turn. now this got me to believe it was my driver side bearing, but it has no play, and i cant tell if its got the metallic grind when its up on a jack bc the brake pad rubs slightly against rotor. so what could it be? wheel bearing or something worse?

My car has 153000 miles.
My car has an automatic transmission.
