It may have something to do with the quality assurance process that has to do with what box they come in.ive bought timkin hubs and inside the box was a skf with skf directions. at this point i think only one of the best know suppliers are making these, the good name brands just resell em. timkin moog skf, likely all the same these days. timkin stopped the 3 year warranty too as far as i know.
