What is the difference between a knuckle and spindle?

처리 내용

The knuckle is the part the spindle attaches to. The spindle carries the hub and bearing(s). Generally the spindle is used on non-driven wheels, but there are some where the spindle is hollow and the CV shaft extends through e.g. Some Nissan's. The bearing(s) and hub assembly are still on the spindle, there will be a drive flange that bolts to the hub. A spindle attached to a knuckle. A knuckle for a bolt in hub and bearing setup. The term seems to be used interchangeably though.
