WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The steering knuckle pivots between the upper and lower ball joints. The steering gear outer tie rod end connects to the trailing end of each knuckle, allowing the vehicle to be steered.
The center of the knuckle supports the hub and bearing and axle shaft.
