sticking MIP CVD (2.5)

[macfjej]

i bought 2 sets of MIP 2.5 shiny cvds (second hand). Anyways one of the four sticks pretty hard when it's moved towards one side of the pin, it's about as loose and free moving as the others when it's straight and when it's moved on the other side of the pin. sooo, yeah, it sticks on one side, no matter how much i lubed it, it still sticks, so i think somthing is warped, or bent. can you guys give me any advice? will the problem fix itself if i install it, or do you guys know which part is damaged and if i should replace it, or even a way to repair it.

anything is helpful right now
thanks
