Whirring Sound After 20+ Mph

The last few days I've been getting a whirring sound after I reach 20mph or more and it gets worse the faster I go. It sounds like my engine is just punching out a ton of RPMS but it's not and I can't figure out where this whirring sound is coming from. I had two tires replaced and a bent rim straightened a few weeks ago but I don't think it's related to that. Any idea what it is or how I might be able to trouble shoot? 61,000 miles.

Could be a wheel hub. Does it make more noise when you turn to one side?

Could be a wheel bearing. When did you bend the rim?

I bent the rim about a month ago. It was straightened out and didn't have noise until this much later. I also searched some other threads where people were talking about a rubber ring in the firewall behind the pedal that got loose.

Swanman, it doesn't not make more noise when I turn to one side or the other.

Annoying driving noises are hard to diagnose without being there to pinpoint location. It could be anything from wheels, drivetrain, tranny to motor, belts & loose parts. I say get some help...take it to a dealer & let them chase the gremlin.

If you had bent rim...were you in accident? Could be related to recent work...

Hub bearing. When you hit whatever you hit to bend your rim, you hit hard enough to flatten a couple of the bearing rollers in the hub. What you're hearing is the flat spots rolling on the races. Replace the hub bearing on the side that has the sound.
