Abstract
Abstract A shock absorber/coil assembly in a motor vehicle suspension includes a fluid cylinder, a piston rod movable into and out of the cylinder, a vibration isolator mounted on an end of the piston rod, and a coil spring disposed around the fluid cylinder and the piston rod. A mount assembly for mounting the shock absorber/coil assembly includes a retainer adapted to be mounted on the vibration isolator and to be attached to a motor vehicle frame, a spring seat adapted to engage an end of the coil spring, and a thrust bearing interposed between the retainer and the spring seat and adapted to extend around the vibration isolator, the thrust bearing including a pair of first and second races and a plurality of balls rotatably disposed between the first and second races, the first race engaging the retainer and the second race engaging the spring seat.
