It’s not that easy, and it’s not about arguing with a signpost. There are some new designs that use sealed bearings in their hubs that are amazing. There are also new (or recent) hub designs using sealed bearings that are quite prone to failure, with recalls, etc. While not a new style hub, some of the early ford 9” rears used similar style non-tapered bearings, and are quite well known for having their axles walk right out of their housings, especially if overloaded. The Ford 9” then went to tapered bearings, and then back to sealed with a better design. There are also plenty of new vehicles that use tapered bearings too, so what does that prove?
With proper design the sealed bearings can be great. And with proper maintenance the adjustable tapered bearings work quite well too. Cass summed it all up very well, there are pros and cons to both.
The newer style green bearings work great. I still kinda prefer the tapered bearings. And they work great too! :D
