Ps4 pro disc drive changing model

Hello. I have a problem with my disc drive, it only spins the cd when i shake it … i believe there is a problem with the thing that spins it, not a motor. I want to change the deck with the laser, just in case. But i am struggling to know what kind of model of the deck do i need. My ps4 pro model is cuh7016b . I believe the laser should be kes496 ? Also if it still will not work, i will need to change the disc drive itself. I have done some research and found that when you change the disc drive , you need to swap some kind of board from the old o e to the new. Is it still in need to ps4 pro ? If yes, where is it in this model, as it seems different.
