So, I called the supplier I was gonna use for the rebuild kit for my 8". They told me that they don't use Timken, but a brand called Koyo, from Japan. Told me it was a very good bearing and used in a lot of modern Fords. This positive review was supported by our fleet mechanic at my work. He specializes in Fords and has been a mechanic for around 40 years. He also said that it was a good bearing; not garbage by any stretch of the imagination. He told me it was something having to do with the type of furnaces they use... they are able to make the steel harder. Thing is, I've never heard of this company. But I haven't heard of a lot of things. What do you guys think? Anybody have expeience with Koyo?
