Rear hub less studs to fit all models

All models of the Mini use the same rear hub (this piece holds the rear wheel bearings). The Mini’s rear wheel bearings are more than adequate, usually requiring only occasional repacking with grease. The weak link may be the cast iron hub; it is not uncommon to damage a hub beyond salvage when removing the bearing. New hubs come without studs, for pre 84 10″ wheel models these would be 21A2064 and for post 84 cars owing to brake drums having a built in spacer 21A1278 For new bearings see GHK1805.
