The cast aluminum wheel knuckle provides the attachment for the following components:
- The lower control arm
- The spring and shock absorber assembly
- The wheel hub and wheel bearing assembly.
The extended lower boss on the wheel knuckle provides for the attachment of the steering gear tie-rod ball joint.
The upper section of the wheel knuckle has a location hole for the shock absorber body. The shock absorber body slides into the hole and locates against an abutment. The rear face of the hole is split and allows the shock absorber body to be clamped in the wheel knuckle with a nut and bolt.
Mounting locations are provided for the brake caliper, the brake disc shield and the brake caliper cooling air duct. A hole in the rear side of the wheel knuckle provides the location for the wheel speed sensor, which is secured with a bolt.
The wheel hub is located in the wheel bearing, which is installed in the wheel knuckle and secured with a circlip. The inner face of the wheel bearing incorporates a pulse ring for the wheel speed sensor.
