If you don't need the truck for everyday use, pull the bearing and take it to a bearing shop. There should be a number on it and if not they can measure it and replace it. You might need a speedy sleeve for the yoke shaft (or whatever it's called) where the seal has been riding, you'll see when you get it out.
