Wheel Knuckle: Removal

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Suspension fasteners are important parts because they affect performance of vital components and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation is necessary. Do not use a new part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
CAUTION: The wheel knuckle/wheel hub is serviced as an assembly. Do not attempt to separate the wheel hub from the wheel knuckle.
  1. For reference during the installation of an upper or lower arm, measure the distance between the center of the wheel hub and the lip of the fender with the weight of the vehicle resting on the wheel and tire assemblies.
