Drive shaft Sound?
 

Hello,
I just bought a nice 98 quattro a8, im a new audi fan! while backing up and sometimes while driving i here a clicking sound and at higher speeds i get a chirping sound that seems to be coming from under the car that goes away when i take my foot off the gas and coast. Any ideas? im more of a jeep guy but i figured maybe CV, u-joint or drive shaft bearing? also it just had a new transmission and control module put in.

Thanks!

Anyone???
