Abstract: A planar joint for pivotally supporting an arm to a support structure includes an outer sleeve with a shaft extending through the outer sleeve and including an integrated washer extending radially outward from a central portion thereof. A pair of thrust bearings disposed against the integrated washer on respective opposite sides. A pair of bearing sleeves are adjacent to a respective one of the pair of thrust bearings. A pair of threaded washers are threadedly engaged within respective opposite ends of the outer sleeve. A pair of seals are received in a cavity in a respective one of the pair of threaded washers. A pair of retaining rings are received in an opening end of the cavity of a respective one of the pair of threaded washers for securing the seals within the respective threaded washers.

Abstract: A dual rate torsion bar suspension system is connected to a control arm and includes a first rate torsion bar and a second rate torsion bar connected to one another in order to provide the suspension system with a dual rate torque resistance. A cam mechanism is employed for isolating the second rate torsion bar from the first rate torsion bar.
