Removal And Installation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Use the hex holding feature to prevent the ball studs (upper control arm, lower control arm tie-rod end and stabilizer bar links) from turning while removing and installing the nuts.
CAUTION: Do not hammer the ball studs to separate them from the wheel knuckle or stabilizer bar. Doing so can cause damage. Lightly tap the wheel knuckle or stabilizer bar to loosen the joints.
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.
