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.
