Wheel Knuckle And Hub
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
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 wheel hub and bearing assembly.
The 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 drive shaft locates into the splines of the hub assembly and secured with a stake nut.
