popping sound coming from front end when accelerating 2000 Deville, suggestions?

I just bought this 2000 Deville and am trying to get all of the small kinks worked out, There is a popping sound that occurs when you accelerate or stop on the breaks in reverse, It does'nt do it when im turning or anything. Im thinking something might need to be tightened but I don't know where to start, I would appreciate any suggestions, Thank you

My car does the same thing if any one knows where to look that would be great.  If im in reverse and hit the brakes it makes a clicking sound sounds like its comein from the front brakes.

to me that sounds like a self adjuster. do you have disc or drum brakes?
