    drone sound from rear of car

    I have an 06 wrx tr. I have noticed a drone sound, almost like a train going down a track real slow, coming from the rear of the car. I think maybe the right side but it is hard to tell. It is not a really loud noise and i can hear it when moving slow, coasting slow, especially parking. I used to notice it first when pulling in my driveway, to the right on a gentle curve and up a mild slope. I have since heard the noise while parking in a lot etc. I don't think it is a constant noise but if the radio is on I'm not sure if it is loud enough to be heard. I am not sure if the sound continues at higher speeds due to the tone and tire noise etc... It is not a squeek or squeel like a brake noise, not a chuck chuck or hum hum, and very consistent almost like a striking a low pitched tuning fork. Any help would be nice. Oh and if anyone knows where all of the brake fluid in my 240 went that'd be cool too (next thing i have to check out)

    car has 61k but has a salvage title, i believe it was hit in the rear, drives fine and was put on a rack and checked out by a friends shop before it was bought and they said everything seemed to be fine

    When was the last time you rotated your tires? If you can, rotate them around and see if the noise follows that particular wheel/tire.

    If not, probably a wheel bearing.

    new tires probably 7 or 8 k ago, put the tires on and took the car from nc to florida with no noise at all, wife thinks maybee the noise started when a stick got stuck under the car backing out of my mom's driveway in va. I changed the rear pads not too long ago and everything seemed to be tight as far as wheel wobble etc....I have been throwing it into turns up here in va fairly hard and have not felt any wobble or anything coming from the rear of the car, it acts nice and feels tight as I drive. If the problem were to be a wheel bearing how much of a job is it to change. Im used to 240's and the wrx seems to be a little needier on the wrenching in most ways. I have tried to see if the noise could be related to a rainstorm or foggy morning etc...thinking maybe moisture getting to the wheel bearing somehow. I think the sound may be getting to be more of a constant thing. I'm going to go jack it up and give it a good visual inspection and shake test today if I have time (moving). Thanks for the input and keep the ideas coming.
