need some long distance help, evil sound coming from rt rear Options

[double-a]

this car has been absolutely trouble-free since we bought it, but today it's got me worried.

for a few weeks, the right rear side of the car has exhibited an occasional "wiggle," usually at freeway speeds. at first i thought it wasn't balanced, but the guys a scwhab do a good job, and it's only an occasional wobble, like it's bouncing up and down. shakes the car real good too.

now, as of yesterday, there's a weird squeak or squeal from the right rear. it's only audible at very slow speeds, such as slowing to a stop, turning into the driveway, etc. it doesn't sound like brake squeal, it's much more evil sounding. but definitely coming from the tire/wheel area.

so what's going on here? bushings, bearings? i'm not real technically savvy, but i can take the wheel off and take a look in there, if someone wants to give me an idea of what to look for.
