The wheel knuckle is an aluminum casting which provides for the attachment of the upper and lower control arms and tie arm.
The wheel knuckle also provides the mounting locations for the following:
- Wheel hub
- Wheel speed sensor
- Brake caliper
- Brake disc shield
- Wheel speed sensor harness and bracket.
The wheel hub assembly comprises a splined drive flange and wheel studs. A bearing is pressed into the knuckle and a circlip positioned to assist in retaining the bearing. The hub is then pressed into the bearing. The driveshaft locates into the splines of the hub assembly and is secured with a nut.
The hub nut tightening procedure must be followed closely to make sure the correct pressure is applied across the bearing for the optimum running parameters to be achieved
