This sounds like there is another suspension component that is causing all this that replacing the rear shocks has altered or dampened the noise. So anytime you change a part, and it makes a difference to the noise then we are at least in the area of what is causing the noise.
The fact that this makes this noise when hitting a bump or dip in the road points to a suspension component and the fact that this is a chirping noise, points to metal on metal.
This normally occurs when these two metal parts are supposed to be insulated from each other so I would suggest starting with checking the upper and lower spring insulators.
Here is a guide that will help with these types of issues. It may not fit exactly but will give us a better idea on what we need to be looking for.
The way to find this is to start isolating components by removing any that are able to be like the rear sway bar and then inspecting any of the rubber components for rub marks and witness marks on metal components.
Let's start with this info and then work our way through it. If you are not able to find anything, can you try to get a recording of the noise? Hearing it may help us pinpoint what the noise is. Thanks
