How to make Ironhide's leg joints tighter?

I'm sure some of you also have this problem with Voyager Ironhide - his automorph legs are abnormally loose and feel like they're going to fall off; one nudge and they move in one direction. someone, anyone, please, please tell me how to fix this. They are the only fault on a movie toy I LOVE alongside my other Autobots; help me make him stronger!
