nuts on the wheel well side, as you remove the bolts from the access opening side that attach the housing assembly to the wheel well structure.
 2)  Have the person in the wheel well remove the bolts that attach the housing assembly to the wheel well structure from the bottom.
 3)  Use a wooden or plastic scraper to carefully separate the support assembly from the wheel well structure, as a sealant certified for a pressure difference between mating surfaces is between them.
 4)  Lift the housing assembly, plate assembly, shaft assembly, and quadrant assembly together as a single unit from the wheel well structure.
 NOTE: Make sure you mark the locations and positions
____ of any laminated shims for later installation.
