The hub assembly is the part that the wheel mounts to. It fits around the axle and carries the inner and outer wheel bearings.
In front wheel drive, a flexible axle spins the inner part of the hub assembly to which the drive wheel is attached. The outer part of the hub assembly is fixed to the steering knuckle. Wheel bearings are in between the inner and outer part of the hub assembly.
In cars without front wheel drive, the front axle is called a spindle. The spindle is a solid shaft that is fixed to the steering knuckle. The front wheel is attached to the hub asembly which rotates on bearings on the spindle.
