Movie 2007 Ice Megatron wing problem

My voyager class 2007 megatron is having a problem with one of the wing hinges which hold the wing tips. In the jet form from top view its the left wing and in robot mode it´s the one on the right as where seen from the front.
The hinge which keeps the the wing tip dangles crazily like the devil is at work
If it tries to stay completely downwards or slanted downwards in jet mode. But if its stretched outwards in a stright line or face upwards in jet mode it stays firm.
I´ve tried tightening/reapplying the screws around this plastic part area but it didn´t work. And I haven´t seen any cracks in the hinge support but i can provide photo of the exact area if it can help, just notify me on that and i´ll provide a image.
Any suggestions ??
