Hi there. Raise up the vehicle and check all of the suspension, sway bar, ball joints, and the shock absorbers. Makes sure that everything is tight. If everything is tight, lower the vehicle and do a bounce test on the rear. Also, check the ride height on the rear of the vehicle. It is possible that the rear springs could be the wrong spring for the vehicle causing the rear axle bumps stops to come in contact with the frame. If the springs are tight, then something within the suspension is binding up or a caliper is loose causing the popping noise. If you need further assistance with your vehicle making noises on bumps, then seek out a professional, such as one from Your Mechanic, to help you.
