so i have this wierd humming noise coming from the front end. starts around 80 kmh and get louder as i get up to 120. over 120kmh it seems to quiet down/ isnt as noticable.

alignment , tires, rims, rotors are all not issues as i have changed everythign recently.

im suspecting wheel bearings? anyone any ideas?

gmsron

Probably bearings. I've replaced both front bearings already. Or it could just be that your tires are noisy.

Does it get worse if you are going around a turn?

salogCL

no. difference around turns.. when slow you hear nothing.. and i dont get a chance to take many corners at 120 kmh lol

is the noise dependent upon rpms?
if it is wheel bearings then it wouldn't be
just trying to make sure if it is or not
when my front wheel bearings went bad in the subaru, it was horribly loud, sounded like 38" mud tires on the highway, and started being noisy around 30km/hr, and it just happened one day.
i couldn't go anywhere over 120, i didn't want anything to break on it, and it would drown out the stereo at 100 or so

its not like a constant rumble or constant noise... tis likea hum hum hum. im gona get all nerdy now,, but its like at that speed the frequency is just right and it comes out as harmonics, 100 is the worst.

im going to jack it up on the weekend and rotate the axles, see if i can hear / feel anything weird.

if it's not constant it doesn't really sound like wheel bearings to me...
but it might be, i'm not too well versed in these kinds of things, just from my experience with my car, it was a constant droning type of noise, not intermittent at all
almost sounds like tires then, since it's only doing it in burts, sounds like the tires reacting to the change in pavement, maybe over the cracks in the road or something
...i dunno, just trying to throw out ideas here

salogCL

its pretty constant like u hear the hum like once every second or two.but 2 differnt sets of tires? the stock ones were really bad, but i just got brand new tires for my 18's but the noise is still there

im just not looking forward to swapping bearing lol

most likely if your wheel bearings are going then you'd be able to lift up the front tires and feel play in the hub when you move it hard with your hands. I'm going through a similar issue myself, and I'm suspecting its a faulty tire...since it's leaking air...either lopsided or cupping or something

yep just lift the tire and pull up and down if they move its bearings i have to get the rear done it sounds bad going 60,65MPR runs loud

Just did my rear hub/bearings. They are extremely easy with the proper tools. DIY and save some $!
