Just like you I started to get a squeak from the back when going over bumps,
Try closing the back door harder or softer, because for me, sometimes the sqeak definitley there and sometimes completely gone. (I dont open the back door often, so I can trace the squeaking to the last time I had opened/closed it.)
I'm not 100% sure that that is the problem but it may be something to consider.
