Anyone replaced the door seals on their X?

[ncal]

I've got an '08 X5 that is just out of warranty. I got most all of the squeaks and rattles taken care of under warranty, but the door seal noise just popped up and is driving me insane. Every small bump makes a squeaking noise til it almost becomes constant.

Searched through the forum and found its a pretty common issue, but didn't see anyone that took care of it themselves. I called the dealer and they want $160 just for the driver door seal, and I imagine at least a half hour of labor. I'll bite the bullet if I have to, but am pretty handy with most vehicle maintenance and wondered if anyone knew where to source the parts? I tried a few sites but couldn't find anything.
