Possible driveshaft bearing?
 

05 545i 6so manual 100k miles. Could use a little help from the experts diagnosing a clink sound I'm getting from under the middle of my car on occasion. I can get it to do it when I'm in second gear and I am on and of the gas fairly hard....I get a clink clink when on and of gas. Sounds like a guibo and or driveshaft support bearing. I have no vibration at any speeds. Am I headed in the right direction.
