The axle beam of the double pivot is bolted to the sub-frame through three triangulated mounting bolts. The axle beam supports the steering box, engine mounting and lower control arms. The tubular cross member and compression struts complete the double pivot suspension frame work.
The double pivot refers to the lower mounting of the strut and spindle assembly around which the wheel turns.
The lower control arm and the compression strut form the two lower pivot points.
The lower pivot point is actually an imaginary point formed by the extension of the two lower mounting arms.
