Why do I hear rattlimg in my controller vibrator?

@jcyrus nobody can tell you how much since it is not yet know what has broken. In general, ifixit does not make any recommendation on who or where does repairs like your controller needs. It would not be objective and invites a lot of spammers that will promise you the world in exchange for your hard earned money. I recommend that you take it apart to check the inside out. This may just be a simple repair that could be done by yourself. Check these guides to work on your controller DualShock 4 CUH-ZCT2 .
