You might check your ball joints / bushings .....I had severe clunking w/ the same issues. When I would brake...no more clunk. Many times the culprit is either the tension strut and or the lower control arms having worn and cracked bushings...this cause metal to metal clunking and rattling. When you brake, it puts tension and loads up the suspension components.
How many miles are on your 08? Remember, we drive big heavy cars, and the suspension will take a beating. I had to change out ALL front and rear bushings (went w/ poly bushings) upper and lower ball joints, upper and lower control arms and sway bar end links. I was good for about a year.....it happened again, clunking until I brake. I never thought to check the bushing in the lower control control arm where the coil over is mounted into. Booth rubber bushings are shot.....sorry for the long winded response, but just might be suspension and not brakes......let us know.
