Abstract: An apparatus and method for use in assembling and disassembling a strut assembly having a shock absorber axially disposed within a coil spring includes a frame, a first section secured to the frame to support one portion of the strut assembly, a second section including a compression head secured to and axially adjustable relative to the frame, the second section including a compression element arrangement to impart a force on a second portion of the strut assembly and urge the spring to compress as the compression head is axially moved toward the first section, and urging structure to move the second section toward and away from the first section. The compression element arrangement includes at least three holders, each of the at least three holders is independently axially adjustable relative to the frame. The compression head includes a spider member having a hub with arms, the hub being secured to the urging structure, and each of the arms being secured to the compression element arrangement.

Abstract: An apparatus for use in assembling and disassembling a strut assembly of the type having a shock absorber axially disposed within a coil spring includes a frame, a first section connected to the frame for supporting the lower portion of the spring, and a second section for holding the upper portion of the spring or upper spring seat. The second section is movable toward and away from the first section and is arranged for axially compressing the spring as the second section moves toward the first section. The second section includes guide structure, a head, linkage structure, and pivot structure. The guide structure is connected to the frame and is for allowing the second section to move toward and away from the first section. The head is mounted on the guide structure and is for positioning the spring. The linkage structure is connected to the guide structure and is for allowing the head to tilt in a first plane generally parallel to the linear axis of the spring.
