Humming, blender type noise could that be wheel bearings?

[albo_bizak]

So i'm hearing this humming, blender type of noise comming from preaty much everywhere but mostly from the rear, I have changed the fluids of my differential and my tranny and there are no leaks comming from either of them. I was thinking can it be wheel bearing, i had my wheel bearing replaced on my alero and my alero before sounds like the supra now. Any ideas where its comming from?

Are you certain that it's coming from the rear of the car and that it is subjective to speed only?

Sometimes, especially on vehicles that have had a blown head gasket, the glycol in the antifreeze eats the oils out of the bearings in alternators and pulleys, which can cause a bearing problem.

If you are certain that it's coming from the back of the car, it could be the following-

-dirty E-brake drums. If you haven't removed the combo rotor/ drums to blow them out and clean them, I would suggest doing that before anything else.

-rear joint/ axle out of balance

-rear wheel hub bearings

-driveshaft joints

-differential bearings

Do you feel any vibration through your brake pedal when stopping?

How in the heck do you rationalize this dude?

Mister: What in the hell are you talking about??? Are you serious???


OP: To check your wheel bearing, jack up the rear of your car and try to move the wheel side to side. If it moves, chances is your bearings are bad.
