I have been packing bearings for years and havent't had much trouble. I was buying some seals the other day for my boat trailer and the ones I had always used had the little spring ..which I found out were called oil seals. The parts man told me I should use grease seals [no springs] . I wound up buying the grease seals but I have questioned myself ever since I made that decision. Does anyone know if it makes any difference? I haven't found any post concering this before and I'm going to use the one I bought [to far to take them back] ..I guess they both work == all they do is keep big rocks out anyway--just joking!! Thanks- have a GREAT DAY !!!
