I"m doing a disc brake conversion and bought new WARN hubs (Too hard to get Aisins for a good price).I have to get the nut and lock washers. So, my question is, do these Warn hubs use the cone washers to bolt on to the hub or is it just washers and nuts? Toyota wanted $107.00 to buy all 12. That to me is BS.Please help me out. Thanks.
