D pad sliding around

I have a weird problem with my d pad, besides the 360 d pad being awful anyway,

It seems like theres too much room in the space where it is, so it seems to shift around while i push to the sides or up, then when I go to push down, it is almost, jamming, sort of, its justnot feeling right when I push it down.

If anyone knows what I'm talking about, or can think of a way to fix this annoying problem, please tell me.

My PSP phat developed that wobble, and my used DS lite i just bought came with that "feature"

I did end up fixing my psp of that. All i did was add one lair of tape to each side of the d-pad to Shim it up so it didnt wobble. I dont think the 360 controller works the same as the psp pad, but you might still be able to tighten it up if you want to open up the controller.
