Go back and read what I said, slowly. It may dawn on you that I didn't say that green bearings were better than tapered bearings.
There are millions and millions of the green style bearings that are used on the street everyday, they come in quite a few new cars as well. That's just a fact, and your basic video with zero actual analysis doesn't disprove that. The way that the majority of people drive these cars on the street, they will never have an issue with the green style bearings.
Are tapered bearings better? For some applications, yes. Like I said in my post, I personally prefer the original style tapered bearings, and that's what I have in my Duster. But, I have a set of green bearings in my Challenger that did 70k street miles and are still just fine, even with 275's on all 4 corners and the car set up for handling and driven on winding mountain roads. They were already on the axles when I bought them and I had better things to do than change out brand new bearings.
The idea that green bearings don't work on the street is just BS. Like anything, for some applications there are better choices. I agree with the video, which is why I install tapered bearings on my cars. But that's not at all the same as saying green bearings aren't ok on the street.
Yeah, if you install anything incorrectly it can cause failures, that's really basic. But in this case, the axles and bearings were NEVER the issue, so this entire sidetrack on bearings is a waste of time.
Before you reinstall the factory springs, take a few measurements.
-Measure from the frame rail out to the quarter lip of each quarter, and see if those numbers are the same. They probably won't be exactly the same, but that's not unusual.
-Measure from the spring to the frame rail on both sides. This number should be the same, or pretty close to it.
-Measure from the spring perch on the housing out to the outer housing flange on both sides of the axle housing. This should be the same.
With those measurements you should be able to figure out if the perches are roughly centered on the housing, if the springs are in the same position relative to the frame rails, and if there's any body tolerance variation from side to side.
Since you only changed the springs, you should be finding the difference in your current set up compared to the last set up with the spring to frame rail measurement.
