Green bearings or stock adjustable

Well, it's about time for someone to cite a certain vendor's technically questionable publication about how terrible stock bearings are and how great the new green bearings are, and btw here's a link where certain vendor sells green bearings

Cass’s description on his website isn’t “technically questionable”, and he certainly doesn’t say the stock bearings are “terrible” or that the green bearings are problem free. Read it again if that’s what you think, he lays out pros and cons for both styles. And both styles do have pros and cons.

Why Green Bearings? - Quality Body Shop Drivetrain

And he sells both types of bearings by the way. I’ve purchased the stock Timken bearings from him. The only thing he mentioned is that the axles I bought would come bare and I’d have to install the bearings myself because he didn’t have the adjusters so he couldn’t pre-install the bearings like he does with the green style bearings.

I had a '70 Road Runner 8.75" that had the green bearings OEM. I know this because I was the 1st person who ever had the rear end apart to replace the 3.23 peg-leg with a 3.91 Sure-grip. Is this "proof"? Besides, GM and Ford used the green-style bearing almost forever. But full-fledged race cars do not count... anything serious has full-floating axles, and when those AARs or TAs were converted to race cars the green bearings were obviously removed. But that isn't how Ma Mopar delivered them from the factory.

Not sure what you remember, but 8 3/4’s didn’t come with “green” style bearings from the factory. I realize “never” is a strong word with Ma Mopar, but if you really did find that type of bearing in your 8 3/4 it was an anomaly, not something the factory switched over to. Find me a factory manual showing those bearings in an 8 3/4, or a TSB or factory bulletin indicating their use.

The 8 3/4’s in my ‘71 Dart and ‘72 Challenger both had tapered bearings, and both appeared to have never been apart previously, both still possessing all the standard factory marks, gaskets, etc. I’ve seen more than a few original, ‘70+ 8 3/4’s with factory tapered bearings. They last damn near forever unless they’re submerged in water, and most of the 8 3/4 axle bearings I’ve encountered have been factory original.
