Front Steering Knuckle: Description and Operation

DESCRIPTION

The knuckle is a single aluminum casting with legs machined for attachment of the strut assembly, disc brake caliper adapter, lower control arm ball joint and steering linkage. The hub and bearing assembly is mounted in the center of the steering knuckle using four bolts. The driveshaft's constant velocity (C/V) stub shaft is splined through the center of the hub and bearing and is held in place using a nut, nut lock and cotter pin.

Service replacement of the front hub and bearing assembly can be done with the steering knuckle remaining on the vehicle.
