Since I have owned my car, the trunk sits a bit higher than the other side. Its also loose on that side, and makes alot of noise while driving. I was wondering if there is a way to adjust it somehow, so both sides will sit flush and snug like it should?

 

Sounds like there are some loose bolts back there or something. Tighten up any loose bolts you find and see if that helps.

 

Is the weather strip still there?
