NOTICE: Suspension fasteners are critical parts that affect the performance of vital components and systems. Failure of these fasteners may result in major service expense. Use the same or equivalent parts if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Tighten fasteners as specified.

1. Using alignment equipment and the manufacturer's instructions, measure the front camber.
   Use the General Equipment: Wheel Alignment System

1. NOTE: If the front camber is above or below the minimum specification, the camber can be adjusted +/-0.5 degree by replacing the upper arm with an upper arm repair kit.

   Replace the upper arm with the +/-0.5 degree camber upper arm repair kit.
   

1. 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).
   

1. Remove the wheel and tire.
   Refer to: Wheel and Tire (204-04A Wheels and Tires, Removal and Installation).
