Who cares - run whatever you want. There is no sense in beating it to death.

Who cares - run whatever you want. There is no sense in beating it to death. Exactly the point I was making. In all these years and all these green bearing bash threads there really has not been a compelling reason to not use either one. If the greens where so bad then all the rear end companies would have stopped selling them decades ago. So, like the previous poster said, give it a rest and use what you want.
In theory, there is no difference between theory and practice. In practice, there is.

The 7 1/4"s came with what looked like a smaller version which many have ran over 100,000 miles The number of vehicles (OEM production)on today's roads that run a "Green Bearings" configuration number in the millions, green bearings have been as hard to accept for the Mopar crowd over the decades, just as hard as accepting disc brakes, never mind 4 wheel disc brakes!, OD transmissions, mini starters, one wire alternators, rebodies, roller cams, non numbers matching drivelines, color changes, or a clean change of underwear!

For those that do not know that the Green type axle bearings, all of them, are ball bearings, nothing more, nothing less  They work, but there not the best for long hard aggressive street or track racing  Think about the contact surfaces on a ball bearing and race and then the same on a tapered Timken roller bearing, how many ball bearings, the O.D. of the balls in each green bearing and how many tapered roller bearings and how much supporting surface contact there is on them   More specific, I believe the Green bearings are double row ball bearings. Years ago I looked up the design specifications for both the stock and the greens. IIRC, the tapered roller bearings had something like 4x the side load capacity of the green bearings. But, the green bearing side loading was pretty high. Again, something like a 4g skid pad type of turn would have to be needed to get to the design load of the green bearing. I know my Road Runner isn't capable of 4g turns on a skid pad. But constant side loading could shorten the life of the bearing. This is going back a ways when I looked this up, maybe like 20 years ago. Finally we are getting some factual data instead of opinions. Both bearing designs will function if used within their design parameters. Due to the design differences their life expectancy will be compromised when they are used in less than ideal conditions. Ball bearings preceded the Timken design by several decades. The Timken design was developed to overcome the shortcomings of the ball bearing in demanding applications. Pretty simple really  they are not double row bearings If not, that only adds to reasoning not to use them.  it should not take a "somewhat" mechanically skilled individual to look at the two "designs" and KNOW which one is the better choice for a particular application.

Valid point, however one must consider the size of the bearings, the weight of the vehicles, their usage etc. IE: An equally sized Timken will easily surpass the longevity of a Ball bearing. That is not to say that a LARGER ball bearing cannot equal the longevity of a Timken. But a Ball Bearing cannot equal the service life when sized the same and subjected to the loads they were not designed to be subjected to, PERIOD!!! Just because the ID and OD match does not mean they were designed for the same use nor will they perform the same. nuff said

GREEN is a company, not just a description, right?
I had to replace the "Green" bearings in my Charger twice in 11,000 miles of spirited street driving. No, not running 70 series bias ply tires or stock suspension....I'm talking higher load stuff like 275-40 18s, 295-45-18s, bigger T bars, sway bars, frame connectors, etc.
I have never seen a tapered bearing fail personally. I intend to switch back to OEM style soon.
