So every time I hit a dip in the road, or pulling out of a driveway, or even anything that causes the car's rear suspension to move up and down...it's squeaks like an abused teenager's bed. It does it at highway speeds too...so I have no clue. It's not super-bad or anything, just a little embarrassing when an 89 lincoln with a blown out rear end even sounds better than my car coming out of a parking lot

I was thinking maybe the springs? LOL honestly, I have no idea what it could be...

Sounds like your rear control arm bushings are gone. Most are by now. I replaced mine and the rubber inside was gone, rotted and rubbed away.
