Lower Control Arms
The pressed steel lower control arm links the subframe to the hub assembly via two ball joints. The inner joint is bolted to the subframe and the outer joint to the hub assembly. The rear of the lower control arm has a hexagonal shaft onto which the compliance bushing is press fit. The compliance bushing is attached to the body with a single mounting and to the subframe with two bolts, which also secure the anti-roll bar.
As the suspension moves, the lower control arm pivots on the inner ball joint. The linear movement of the suspension is changed to rotational movement of the lower control arm, which is controlled by the radial stiffness of the compliance bushing.
Should replacement be necessary a new bushing and housing assembly will be required. Both ball joints are available as separate service parts.
