I'm looking to replace my front wheel ball-style bearings on my '61 GMC 1/2 ton in the near future. It looks like Rockauto has Federal Mogul National brand bearings in stock (P/N's B66 & B67). Based on my research, 1960 & 1961 were oddball years and there appears to be no tapered roller bearing retrofit kits. Unfortunately, these Federal bearings are Chinese made. I've researched online and haven't really found any feedback on this brand of ball bearings. I guess that's a good sign? Normally with a failure there would be a ton of feedback. Does anyone have experience with Federal ball bearings? Yes, I cross-ref'd to Timken, and the Timkens are of the sealed design, and won't work. Any feedback would be appreciated. Thanks!
