To do this, nothing too complicated. You will have to, as you guessed, go to the newly implanted fault, then head directly south, into a metal building, close to the sea. At this point, close to the TV, on the ground floor, you can get Claptrap's eye there. To bring him back, head northwest, towards the end of the rift, at the Welcome panel. All you have to do is give him his eye to succeed in this challenge.
In order to clarify all this, we offer you a map, with the exact locations of the robot and its eye.
