Update #2: after I finished the job described in my previous post, I found there still was a noise from the rear cargo area !!! looking at all the plastic parts finally I found the noise source was from the cargo area cover (the one that covers and folds at top of the whole cargo area)
This cover had a small sideways movement that was making the noise against the plastic base where it seats, so I took a couple of some small pieces of a "foam-cushion-tape" and install them on each side, now I really can say noises are 95% off, check the following picture, you will see the small stripes of tape
