Removal
WARNING: Do not apply heat or flame to the shock absorber or strut tube. The shock absorber and strut tube are gas pressurized and could explode if heated. Failure to follow this instruction may result in serious personal injury.
NOTICE: Suspension fasteners are critical parts that affect the performance of vital components and systems. Failure can result in major service expense. When replacing suspension fasteners, use the same part number or an equivalent part number. 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.
