Removal and Installation
CAUTION: Suspension fasteners are critical parts because they affect performance of vital parts and systems and their failure can result in major service expense. A new part with the same part number must be installed if installation becomes necessary. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
CAUTION: The upper arm is a 2-piece design and is replaced as an assembly. Do not remove or loosen the nut and bolt that joins the 2 pieces together. The assembly is set at ride height during production, loosening the nut and bolt will disturb this setting.
