Squeak from rear - not sure what to check

[Bruce Wayne]

have you checked the pads to make sure the anti squeal shims are intact ?

Hmm.. i can check them, but doesn't sounds like brake pad squeal (which I would only hear when the brakes are applied). I hear this sound with any forward motion, brakes or no brakes.

WAG - while I'd expect more of a hum like sound, could it be a wheel bearing? Does the pitch change in your turning left versus right?

[stateofidleness]

Definitely not the "common" wheel bearing "howling" sound. No difference while turning, left or right.

Really hard to describe... sounds like a squeaky wheel on a wagon, but it's not high pitched.

Will have it up on the lift tomorrow and will get a better look, but could a dry CV, either inner or outer, be a possible culprit? Tie rods, ball joints, maybe?

Does the car have to be moving for you to hear the squeak? Asking to rule out a bearing noise coming from one of the auxiliaries in the front of the engine?

[stateofidleness]

yes, car must be in forward motion. usually becomes audible enough at 5-10mph when in the car.
