Squeak coming from left rear wheel... bearing?

[ldzpstnr]

Tonight while I was out driving all of the sudden this squeek/squeel noise started coming from my left rear wheel. I am going to jack the car up and take a look at it tomorrow. Now this sound is a pulsating sound, not a constant squeel. So I am thinking it oculd be one of three things: Wheel bearing, CV joint, or maybe the parking brake shoe. Now is the parking brake shoe on both wheels or just one side? From what I was told the parking brake shoe is only on the left side.... but I may be wrong. Any thoughts guys? Anyone had a wheel problem like this?

ive got a similar problem on mine. it squeaks according to speed (faster squeaks at faster speeds). and goes away when i step on the brakes.

the parking brake is on both sides, it had what is like a small drum brake setup for the parking brake.

Poboyis mentioned the parking brake - I had the same problem on mine after I had over-adjusted the parking brake. Not necessarily the problem, but it's easy to adjust by pulling up on the E-brake boot and using a deep walled socket to adjust the nuts.
