Upper Arm: 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 critical parts because they affect the 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.
NOTE:
The suspension upper arm bushings or ball joints are not serviced separately from the upper rear suspension arm. If the bushings or ball joints require service a new suspension upper arm must be installed.
- Remove the hub cap. Measure the distance from the center of the hub to the lip of the fender with the vehicle in a level, static ground position.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
- Unclip the ABS sensor wire retainer from the suspension upper arm.
- Remove the ABS sensor bolt and the ABS sensor. Position the sensor aside.
- Remove and discard the upper ball joint-to-wheel knuckle nut, then disconnect the upper ball joint from the wheel knuckle.

CAUTION:
Use care not to damage the anti-lock brake system (ABS) sensor ring. A damaged sensor ring will result in incorrect ABS operation.
NOTE:
Use the hex holding feature to prevent the ball joint from turning while removing the nut.
