Abstract:
A dual bearing strut assembly for a vehicle suspension system includes a strut with a shock absorber comprising a damper cylinder and a piston rod, and a coil spring disposed around the shock absorber. The damper cylinder may be affixed to a knuckle of a vehicle wheel assembly and the piston rod may be affixed to a top strut mount. An upper bearing assembly and a lower bearing assembly are included. The coil spring has an upper end seated to the upper bearing assembly and a lower end seated to the lower bearing assembly. The lower end of the coil spring freely rotates about the damper cylinder when the coil spring is compressed thereby reducing torque on the damper cylinder and reducing “bump steer” of the vehicle steering system.
