NEVER bash at the inside face of the hub to try to hammer it off the axle. It will wreck the circlips retaining the inside end of the axle and also cause damage to the slot/splines where the circlip is fitted. Find someone (farmer engineer?) who has a really powerful (e.g. hydraulic) puller and exert the pulling force on the hub close to the axle, where the hub is strongest - i.e. do NOT attach the puller grabs/hooks to the outside rim of the hub or you could bend or break the hub.
