if you did get it apart you have to figure out how your going to weld it back together again and seal it. there is lots of stress on the joint from concrete weights and heavy washing etc
as for the bearings they should not be a problem as they will use standard sizes but the water seal would have to be sourced from somewhere. it may be common one but you would need the numbers off it
