Creaking Noise in Rear End

[xTOM153x]

This problem started happening a couple of days ago and has gotten progressively worse. I wouldn't mind if it only did this when parked though it's so loud even when I'm driving. Every little body roll or bump or anything it will make the creaking sound. To make things easier I uploaded a video on the noise at the link below. The noise seems like it's coming from the drives side rear wheel. Just wondering if anyone has experienced this because if it's the shock and strut I would like to replace them asap since I need an alignment soon. Any help would be very appreciated. Thanks

your spring cracked? I thought that was a 02 issue though. (could be wrong)

( I didnt watch the video)

The rear springs look fine. Its just seems like the sound is coming from there I can't pinpoint the exact location but its in that area. I'm going to try and pinpoint the problem this weekend when I have some more time. I was just thinking and it could possibly be a worn sway bar bushing but I have yet to check.
