9. Relieve tension on spring compressor and remove control arm attaching bolts and control arms.
b. Installation
NOTE: Fasteners in subparagraphs b are important attaching parts in that they could affect the performance of vital components and systems, and/or could result in major repair expense. They must be replaced with one of the same part number or with an equivalent part if replacement becomes necessary. Do not use a replacement part or lesser quality or substitute design. Torque values must be used as specified during reassembly to assure proper retention of these parts.
1. Attach lower control arm to front spring eye. Torque bolts to 18 lb. ft.
2. Install spring compressor on spring and compress spring to appropriate length.
3. Raise jack with spring compressor, spring and control arm assembly into position under the car.
4. Install lower ball joints and torque nuts to 40 lb. ft. Install new cotter pin.
5. Attach lower control arms to frame cross member using new lock nuts.
6. Attach both shock absorbers. Torque bolts to 30 lb. ft.
7. Remove spring compressor.
