2011 CRV bearing noise?

[WhyMe]

my 2011 crv has a humming noise that inscreases and decreases with speed. i think it might be a wheel bearing ,but how do i isolate it from tire noise? i have jacked up all 4 corners and checked for play and noise when rotating, but i can't find any.

any suggestions?

Get going at least 20 mph then swerve back and forth at least a couple of seconds per side. If the noise is there on one side and not the other then you can isolate the side that has the noise. Empty cul-de-sacs and roundabouts work for this too.

Noises are some time a pain to sort out.

If you have 4wd it could be part of that system as well.

it is AWD. i wonder if i put it up on stands on all wheels and ran it would that work to help me figure out where the noise is coming from. or is doing that dangerous.

Same with my 2012 Accord, but the noise does not change when swerving side to side.

have you been servicing the AWD system with Honda duel pump fluid? I have heard a lack of servicing will make it fail and it will start sounding like a duck as you drive. (not my description), but a hum might be the onset of the duck noise.

Sometimes bad bearings can identified by slop/play but sometimes they can be bad even without much play.

I would put it up on 4 jackstands. You can try running the drivetrain, assuming you are on nice strong jack stands but our '13 Focus detected the car wasn't going anywhere and wouldn't let us keep the wheels moving. You'll most likely hear enough with a partner hand spinning each wheel/tire for you while you use an automotive stethoscope underneath- they can be had on ebay for around $10. You put the stethoscope on the hub/knuckle or wherever the bearing is housed. In our '13 focus, I identified a bad a bad right rear and the noisiest one was actually a 'center bearing' on the right drive shaft... easier to just buy a new Motorcraft axle than to try to replace the bearing.

I've got to do this exercise on the Subaru as there is a noise that is just too hard to identify running down the road.
