Weird noise. CSB? Help please!

[frickendom]

I am getting rough metallic sounding/grinding upon acceleration. Sometimes it goes away, and sometimes it comes back. I suspect its a CSB, but it doesnt make vibrations or thumps onto the floorboard. What are the symptoms of a worn out CSB(Center support bearing) ?

Here are the sound clips guys... Please help me diagnose this sound!

Get the car up in the air and inspect the drive train for signs of rubbing. Bad motor or transmission mounts may allow things to move enough to rub.

I already had two shops have a visual inspection of the underbody and reported back with only balljoint/ tie rod boot ripped. I am going to replace both control arms. I dont think the control arms can cause such a noise. Yesterday I took the wheel off and spun the disc and fiddled with the brakes. I am not the mechanical type of person, but i am getting there.. After I fiddled with the brakes, I drove it around for a good 15-20 mins and the noise did not occur. This morning I drove it to school (2 miles)with no noise, but after school driving it home, a slight noise came back. But no where near as loud as it was in the sound clips...
