Really? I was not aware of that. I like Rick a lot. But he's wrong about that, IMO.

The sealed ball bearings used on all modern cars are not single row ball bearings. They are double row ball bearings (angular contact) with deep groove races and designed to take side loads. One row of balls takes a thrust load in one direction, and the other in the other, so when you are placing a side load on the bearing in either direction there is a thrust bearing taking the load.
The commonly used ball bearings used to replace tapered roller (thrust) bearings in mopar 8 3/4's are NOT thrust bearings. They are single row shallow race radial contact bearings, and with extended side loads will fail.

Although "green" bearings resemble other sealed wheel bearings, they are internally a very different animal.
Okay, thank you. I've done a little more looking around and I found this and it appears to coincide with what you (and some others) are saying.

Learn sumffin new everyday cause I didn't even think the older style (RP 400) was still bein made. lol
Summit Racing carries both, and oddly enough the older ones are literally 2X the price (well maybe not too odd, since Mopar is the distributor).
MILLIONS of Ford, GM and Chrysler vehicles came stock with single row ball wheel bearings in the rear.
Okay. Any particular reason? Just on this point or do you generally disagree?
Millions of vehicles have used the ball bearing green bearings on the rear of front wheel drive cars. Single row, ball bearings JUST like a damned green bearing. Come up with all the excuses you want, that's the fact.
GM, Chrysler and Ford C-CLIP rears use straight ROLLER bearings that ride directly on the axle shaft.
Millions of GM, Chrysler and Ford NON C-CLIP (retained wheel bearing type) rears came stock with sealed, single row ball wheel bearings.
Single row ball bearings are MORE common in OEM retained wheel bearing applications than the tapered roller type. I never said ball wheel bearings were stronger than tapered roller wheel bearings.
Most people will never notice a functional difference between the 2 designs.

In 40+ years of servicing vehicles,, I have replaced about 2 dozen worn out front tapered wheel brgs... apprx $20 a set..
In the last 10 yrs I have replaced at least that many front (ball bearing) hubs, plus a coupla rear hubs.. avg $120 each..
I've come to the conclusion that the ball brgs don't last as long as tapered roller bearings,, perhaps cuz the "hubs" can't be serviced (repacked), but not sure I believe that... jmo

lol thats why circle track cars with 9 inch rearends use a tapered bearing rusty......oh wait yep 9 inch ford used a green bearing and they like this debate go round and round and round putting ungodly amounts of side loads on the bearings. If rick started it it was because he had a butt load of them he wanted to sell.
ran green bearing in my dart for well over a decade with no issues. rear will go into another abody sooner or later and those same green bearings will be on the axles..
I'm not sure I follow you. I know you're being sarcastic, but it's difficult to read without proper punctuation. Are you saying that Rick E. started this debate? He didn't, he just made his thoughts known on the subject. I'm not his lawyer, but I think he's allowed to do that. I don't think that the debate is over whether a tapered bearing is better than a ball bearing for this application - because I think that's settled ... it is. The debate is really over whether the ball type is adequate or not. I had not posted in months as you can see, and nobody ever answered my last question as to whether or not replacing the older type of Green bearing I have now with the latter type is worth my effort.
I wouldn't replace until I saw a problem.
