Rear suspension squeals, kyb shocks/strut mounts Options

[liquor]

i hear an annoying sound from the rear shocks (from the top, both sides) when i hit light bumps (like rubber pieces squealing), most of the time when its cold outside. I replaced all shocks with kyb gr2s 2 years ago and the problem appeared 1 year ago and its getting worse. I had the strut mounts replaced too (KYB) at that time. I went to the dealer and they told me it was the top plates (is it the same thing as strut mounts?) Anyone has an idea of what could be the problem?

I have a clunking/kind of squeaking (at times) sound coming from the back of my car as well. My mechanic said that my hatch was a bit loose. The plastic in the back isn't properly aligned with the hook on the hatch and also sits a little higher than it should. He told me to try to loosen some bolts on the back of cover and try to bring it down so that the hatch could close more properly. I didn't really listen to every word he said because I was in a hurry, but maybe someone else knows something about this. He said it was definitely the hatch because I just had my struts/shocks replaced (along with mounts/boots and springs).

Also, this sound was from before and after the suspension work.
