Abstract
A vehicle strut assembly includes a boot and a coil spring. The boot has a vertical wall, a spring receiving portion and a centering portion projecting from the vertical wall. The coil spring has an end section, a transition section and a main section, the end section being fitted to the spring receiving portion encircling at least a portion of the vertical wall and defining a first radially inner diameter. The transition section has an increasing inner diameter extending from the end section to the main section. The main section defines a second radially inner diameter greater than the first radially inner diameter. The centering portion is positioned to contact a radially inner surface of the transition section of the coil spring restricting movement of the end section of the coil spring relative to the spring receiving portion of the boot.
