Not sure if this has been covered over here or not but just in case. A guy over at JBL found a nice fix to the lack of range of motion in the Wraith elbow joints. He simply (and carefully) popped off the forearm armor and discovered that the forearms were positioned backwards. Simply rotate them around, slide the armor back on and VOILA! better range of motion.

I was able to spin my forearms around by pinching the armor and spinning them just a little bit at a time. Mine works great and the hoses have not broken. It looks like he cut his.

Clear Wraith is another story. It seems those really are frozen in place.

I'm waiting til I find another, before I start hacking up the one I managed to find.
