Squeaky rear suspension?

[Jersey John]

I'm hoping I don't get flamed with this line of questioning; but here it goes:

I have a 2013 X5 xDrive35i and I've been hearing a slight squeaking in the rear area when I'm driving down imperfect roads. It's especially noticeable at lower speeds and it's not as much with potholes but with certain undulations in the road.

For a while (and even now, still) I've thought it was related to my rear hatch. So I've searched and searched and found all the different adjustment points for my upper & lower rear hatch; but to no avail.

I've started considering if perhaps it was related to any suspension components; perhaps bushings or something of the sort. I'm wondering if anyone else here has experienced something similar to this and would appreciate some feedback.

And, as I say to my kids: if you have nothing nice to say, then don't say anything at all.

Thanks in advance
