Note: All spring attachments, including control arm ball joint stud and control arm bushing bolts, are important attaching parts in that they could affect the performance of vital components and systems, and/or could result in major repair expense if installed incorrectly. They must be replaced with parts of the same part numbers or with equivalent parts if replacement becomes necessary. Do not use replacement parts of lesser quality or substitute design. Torque values must be used as specified during reassembly to assure proper retention of these parts.
End cap bolts should not be tighten until vehicle is on the ground (and entire vehicle weight is supported by vehicle springs (motor installed and body panels on)).
