Possible Wheel Bearing? Whirring Noise...
So, I've noticed lately a strange whirring noise when I'm driving at speed. It's most noticeable around 35-45, then again at around 55-65. It's tough to figure it out, because of the excessive road noise caused by shittily paved highways and my shitty tires, but I'm concerned it might be a wheel bearing going.
The noise itself is a slightly higher pitch than the normal road noise, but instead of the steady drone you get from said road noise, it's more of a whirring, wobbling sound. (thing waawaawaawaawaa instead of waaaaaaaaa)
The mechanic I spoke to over the phone said I could bring it in and he'll replace the front wheel bearings and see if that's it. That's all well and good, but I'd hate to spend the $400 quoted if that's not the issue, or if it only needs one.
