Upper Arm: Removal

NOTE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent parts, if replacement is necessary. Do not use a replacement 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.

Measure the distance from the center of the hub to the lip of the fender with the vehicle in a level, static ground position (curb height).
