Now slide the housing out of the way, and you will find the cause of this whole mess: four bolts. These four miserable bolts (two on top and two below) have a tendency to loosen up over time. Using a torx bit or a 11/44-inch socket, remove these guilty bolts, then slather them with some red Loctite. If all is done right, these bolts should never cause you another problem. But the job is only half done. Now we get to put all this stuff back together again. If a digital camera was used, now would be a good time to scroll through the photos and see how each piece fits.
