Creaking noises in the cabin?

[JGard]

I've had my X5 for about 4 months now and I love the thing. However, something is really bugging me about it, and I haven't mentioned it to the dealer yet as I figure they won't do anything about it (although I'm still under the maintenance plan and I bought an extended warranty).

Basically put, whenever I make a turn, I hear a ton of creaking noises from various locations in the car. mostly it sounds like it's coming from all the doors as well as the trunk. It almost sounds like (for those of you who remember CDs) if you had a CD package in the lower door pocket and it would tip from one side to the other as you turn. It's just like that except there's nothing in the lower door pockets. Is this normal for these?

I've used the Gummipfledge stuff to "fix" the rubber seals thinking that may be it, but to no avail. Not sure what other options I have (and I hesitate to take the doors apart, although I'm mechanically inclined enough to do it should I have to)
