Minis with drum brakes use this drive flange. You may also require the spacer on which the inner seal runs.
The front hub bearing in this version uses the shaft that is part of this flange as the surface for the inner race.
In this version the splined smaller CV joint slides into the flange. The problem with this is that if the wheel bearing end float is not tight enough then the bearing will spin on the shaft and destroy it! The shaft of the flange should be perfectly smooth with no steps or grooves.
