Removal
NOTICE: 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 part, 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.
NOTICE: Orientation of the suspension fasteners is important. Make sure the fasteners are installed in the same direction as they were in when
removed, or incorrect clamp load and component damage may occur.
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).
2. Remove the wheel and tire.
3. Position a suitable jack under the wheel knuckle and raise the suspension until the distance between the center of the hub and the lip of the fender
is equal to the measurement taken in Step 1.
4. Remove and discard the upper arm outboard nut and bolt.
5. NOTE: The inboard nut that is installed at the assembly plant is a flagnut. This flagnut is used to set and maintain the rear camber settings.
Discard the flagnut and install a non-flagnut to allow the rear camber to be adjusted.
Remove and discard the upper arm inboard bolt and flagnut and remove the upper arm.
Installation
1. Position the upper arm and install a new inboard bolt and non-flagnut.
