Ok, I just changed out my axles with DSS Stage 1 axles, which I thought
would have fixed the buzzing sound I have.

It didn't fix it. Now I'm thinking that it is something else. It makes it regardless
if I have load on the tranny or not at ~40+ mph. Really loud.. It kinda sounds
like a flapping piece of plastic buzzing from wind. (kinda like a reed from a musical
instrument).

Does exhaust leaks sound like this?

 

mabey a loose bolt rattling

 

thats sounds wired man. How do you know that its the axles? Maybe time for a tranny rebuild.

could it be your antenna? mine makes a certian noise right around there and it bugs... your exhaust leak would sound like air blowing thats under pressure.
rev your car w/ the passenger side door open and you should hear it if thats the problem.

Good Luck w/ this one!

Yeah I had a bolt on the gravel catcher under the car that would flap over 40+, One question though does it do it in neutral? Also check ur disk brake covers they might be bent or somethn.

 

Gravel Catcher?

My disk brake covers are bent.. does it really make this sound?

It doesn't do it in idle...
