when i take off slowly i get this wierd creaking noise

could it just be worn out bushings or something else?

 

I've got the same type of thing going on, I have noticed it much more since I swapped a miata LSD in, and I used the competition diff mounts. Not sure if they are making the noise or what, but I haven't noticed anything strange with the handling. It does this creaking when I take off slowly, or even when making a turn. Finally today I was bothered by it, since work is slow, I'm going to try and jack it up and torque everything and give it a once over.

Did you ever figure it out? How many miles on your car?
