Front Drivetrain noise

[cruiser787904]

My 05 Denali is making a noise from 5 to 30 mph as well as 30 to 5mph. It sounds like marbles in a can and it does it most of the time but sometimes not as loud. It has to be in the front drivetrain and is definitely more prevalent when driving by a wall or another car. If I am on the gas it goes away and when I am coasting it is most prevalent. The noise is still there under braking as well. Is this CV joints, hub bearing or?????

I am about to throw my struts and shocks on soon and need a quick run down on what to check and probable causes. I am a newb to 4 wheel drive vehicles so any help on what to look for would be great.

Thanks in advance:tiphat
