Timken bearing issue

[ga-stepside]

I spent hours searching for Timken bearings for the rear axles. I finally found the part number for these from Timken is 6408. I found them on Amazon with next day delivery. They arrived today in Timken boxes marked 6408 but when I opened the boxes they were both Koyo bearings, same as what I took out of the truck. Research says this happens a lot and a couple posts said Koyo bought out Timken. I went back to Amazon and found 5 different manufactures with that same part number.
