ABSTRACT:
This invention relates to a retaining sleeve which is utilized in conjunction with an associated threaded cap to hold a replacement shock absorber within the cylindrical shroud of a vehicular suspension system of the type commonly referred to as a MacPherson strut suspension system. The retaining sleeve includes a hollow cylindrical upper member and a hollow cylindrical lower member. The lower end of the upper member is provided with collet portion having a plurality of radially movable arms. The collet portion has external tapered formed thereon for engagement with internal tapered threads formed on the upper end of the lower member. The relative rotation between the upper and lower members in one direction causes the collet arms to move radially inwardly to securely grip the outer wall of the cylindrical shroud. After a replacement shock absorber is inserted within the cylindrical shroud, the threaded cap can be secured to the upper end of the retaining sleeve.
