Front Steering Knuckle: Description and Operation

DESCRIPTION





The knuckle (1) 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. The knuckle also has two machined, drilled and tapped legs on the leading end casting to support and align the front disc brake caliper adapter.

The knuckle supports the wheel bearing (5) and hub (3). The hub is pressed into a sealed-for-life wheel bearing that is pressed into the knuckle. A snap ring also holds the bearing in place. A shield is pressed onto the knuckle behind the hub.
