Front Steering Knuckle: Description and Operation
DESCRIPTION - STEERING KNUCKLE (FRONT)
The steering knuckle is a single casting with legs machined for attachment to the front strut assembly on the top, lower control arm ball joint on the
bottom, and steering linkage on the trailing end (Fig. 1). The steering knuckle also has two machined abutments (rails) on the leading end casting to
support and align the front disc brake caliper.
The knuckle supports the wheel bearing and hub (Fig. 1). The wheel hub is pressed into a sealed-for-life wheel bearing that is pressed into the steering
knuckle. A retainer plate also holds the bearing in place. The hub supports the driveshaft outer Constant Velocity (C/V) joint. Each is splined and
meshes in the center of the hub. The outer C/V joint is retained to the hub using a nut. The nut is locked to the outer C/V stub shaft using a nut retainer
