Front Steering Knuckle: Description and Operation

Steering Knuckle:

The steering knuckle used on this vehicle is a cast iron casting. The steering knuckle has machined legs for attachment to the McPherson strut and lower ball joint. The steering knuckle also has machined abutments on the casting to support and align the caliper for the front disk brakes. The steering knuckle also has the bearing supporting the front hub and outer C/V joint of the drive shaft pressed into it. The hub bearing is a press fit into the steering knuckle but is additionally geld in place by a retaining plate bolted to the front of the steering knuckle. The hub is positioned through the bearing and knuckle, with the outer C/V joint stub shaft splined through the hub. The outer C/V joint is retained to the hub using a nut. The hub nut is held on the stub shaft using a nut retainer and cotter pin.
