Abstract: An adjustment for a MacPherson strut of an automobile is provided by modifying the top bearing retainer to provide an inward circular lip. Two plates are clamped to this lip. Before clamping, the plates are rotatable relative to the bearing retainer so that the center of an eccentric hole therein moves along a circle which is concentric to the bearing retainer and thus the bearing. The upper end of the piston rod of the strut is mounted in the eccentric hole so that the position of the upper end of the strut can be moved relative to the body and also within the bearing and helical spring.
