Mark each motor according to where it attaches. The rumble motors are different so they will not work if you switch them.

Take note of where the red and black motor wires attach because they should be reattached in the same order.

Turn over the controller so that the thumbsticks are facing down.

Use tweezers and a soldering iron (Soldering Iron Guide) to remove the black and red wires from the motherboard.

This will release the rumble motor from the controller assembly.
