At around 40mph I can hear and slightly feel a humming that is coming from the front of my Fiero. I am pretty sure it is not the tires, I hear it regardless of the road I am on. And, I can feel it in the floor.

Bearings?

Do you hear it steering a little left and right? usually you can make a bearing noise go away at some steering angle.

Maybe... pretty easy to check for play and noise (jack up the wheel)... or just change out the bearings.

What is the history of the car?

Did you swap tires from front to back, to see if the noise changes?

No pulling but some wear on the outside of the driver's side front tire.
I had an inspection at in April and there were no problems. They check
for wheel play.
Last year I did have some play in one side and I tightened the nut a little.
But I was told there was some play in it and to do so.

Just did this on my '84. The bearings would hum at certain angles intermittently, I had no play in my wheel, but changed the bearings anyways. Problem solved, cheap and easy fix.

If the bearings were too loose or too tight, they could have worn. They are cheap to replace. Be sure to follow the service manual when tightening the castle nut.

If a tire is wearing you probably need an alignment.

Yeah, I kinda know I have alignment issue.

Can a bad wheel bearing cause tire wear?

I only drive about thousand miles a year. Not sure why this suddenly started, except to say last year I tighten the bearing after my mechanic said I had some play. I'll do a bearing replacement this weekend and see what happens.

Could be too tight then since you just tightened it, my guess.

Did the bearings in both sides. No humming, in fact sounds and drives great. So I know it was the bearing. On the side I suspected I removed the wheel and I could feel a clocking when I rotated the hub. When I removed the bearing there was no visible damage. But, it is fixed. Simple to do, cost about $40. I got some good Mobil One grease.

Could be... might not be front. Sound/feeling isn't best way to tell. Either can lie.

See my Cave, Front Bearings

If you sure it not any tire...
Rear hub(s), axle bearing in trans, or damage axles can make noise/vibration.

Thanks Orge.

Pretty sure that was it. The noise and humming was pretty predictable and constant. I did read your Cave post on the front bearing.

More interested in what caused it, but the roads up here are very punishing on a car. I have to raise my front suspension a little, and still the potholes are punishing.
