Best type puller for 28-48 hubs is type that clamps on groove in hub,even better than 3 leg type.But I have always managed to get them off by using a home made KO puller.You have to keep the puller tight,jack up the other side,stick 2 screw drivers between drum & B P and keeping pressure on the screw drivers with your knee & 1 hand, hit the K O a good swat or two with a 4# hammer.Ive always been able to get them off this way.The odd time Ive had to heat the hub to get them off in extreme cases.
