It has been reported that the green bearings will not handle the side loads that the tapered roller bearings will. While this is definitely true, I don't know how much more the rollers will h andle and whether it matters on a street car. I will continue to run the original tapered rollers.

If you can reuse the stock set up I say go that direction. They were a great design, which is why so many people swear by them. Especially if you can reuse the ones already in there by just repacking them. On the other hand, if for some reason you can't use the stock tapered set up, don't worry too much about running greens. From what I understand most modern rear wheel drives use them from the factory. I've had green bearings in my challenger for many years. I used the non-snap ring style. Same set for 18-ish years, and probably 100,000 miles of daily driving and Friday night red light to red light abuse. In my case, the housing I swapped in had been adjusted wrong and allowed the outer race to spin wearing out the seating surface in the housing end. Greens were the perfect fix. That said, I do have one side making some funny noises now, but after that many years and miles I'll happily put new greens in when I go through the rear again instead of buying another housing.

Been swapping Greens in for quite a few decades on Mopars, not a single failure, or issue...but again as with anything mechanical, abuse, improper installation, etc, etc, can lead to failure
Detroit has installed Millions of Green bearings, haven't heard about any massive recalls yet?

Tapered roller bearings are unbeatable when side thrust pressure is considered. All of the high speed passenger trains of the 50's and 60's traveled on tapered roller bearings made by Hyatt, SKF but primarily by Timken. The same brand mother Mopar installed.
If you only travel in a straight line, your car is a trailer queen, or if you really really need disc brakes on the rear and need more clearance, Green bearings are just fine. They are not that horrible to change out anyway.
As previously posted, if properly greased, rollers will last a very long time. The exception is if they get drenched in water due to seal failure.

When I first saw the Greens 30+ years ago, I freaked....I thought they would fail catastrophically and you'd lose a wheel. Turns out, that, while they are nowhere near as beefy and long-lasting as the OEM Timkens, they do give plenty of advance notice (noise) before they totally fail.
Still, I have personally never seen one last more than 10K or so in 'real street' use, 5K is more typical. I have changed plenty of 'em, whereas the stockers last nearly forever with good grease and reasonable endplay adjustment.

First generation(RP-400)Green bearings, still sold by Mopar Performance, are problematic because the crimped on flange will not allow the bearing to wiggle around inside a housing that is not perfectly straight (none are). In addition, the design causes the axle to be inserted DEEPER into the housing than necessary. This results in pre-loading against the differential thrust block. Second generation (MO-400/ST-400) snap ring style Green bearings are more forgiving because they can move around inside the housing and they do not preload the differential thrust block in a stock application. Most guys who have problems with Green bearings are running the Mopar Performance version or incorrectly made aftermarket axles, housings or poorly designed rear disc brake kits (ie. Wilwood), all of which cause pre-loading and premature bearing failure. I have several customers running MO-400 snap-ring Green bearings in daily drivers. The design is no different than what came stock in millions of other vehicles, including '60s era Mopar 7.25" rears. http://www.rockauto.com/catalog/moreinfo.php?pk=221853&cc=1496034

Agreed....I have over 40,000 miles on the set in my 70 Charger (DANA 60 SSBC rear discs)...plenty of street miles, cross country runs, and assorted Autocross/Track events...no issues, again any componet can fail if the application is improperly chosen, and/or installed improperly, or just severly beaten...I've tosted more factory tapered bearings than I can count in Dana's or 8.75's...I have to date never had a failure of a Green Bearing on my car, or customers builds...

I drove my Duster on the street with the green bearings from Strange Engr.(they have the locating clips on the outside of the bearings 
) with a spool for 7 yrs, not a lot of street driving(less than 3000 miles on the street probally) but quite a bit of drag racing, no problems with them 
I have been working on Toyota pick-up trucks for thirty years that use the same basic design and have very few troubles with them and some of the trucks I work on are beat to death daily.
