I second the motion. I replaced to greens at least a decade ago. So far I have years of autocrossing, two track days as well as tens of thousands of miles of spirited driving - no failure yet.




A friend's car I installed a Wilwood disc brake kit on (which required snap-ring green bearings) is currently on its 4th set of bearings in under 2 years. The previous set (the 3rd) survived road use and drag racing easily. But rally and spirited driving killed it in ONE DAY.

My car did the same with tapered bearings (no rear discs), and they're still fine. They're at least 15 years old.



First a question and then a comment with more questions Are Green bearings a "brand of bearing or a style that uses a typical sealed ball type bearing? Does Green manufature their own bearings or do they buy them from vendor and assemble the kits? I tried googling Green bearings and only came up with forums like this one or old history (1930s) about the original Green company. Who makes these bearings??? ok several questions...

I ask these questions because I'm really torn here. I have seen testimony both ways. As people are using these ball bearing under condition that are considered by many to be adverse to their design, I have to wonder if there aren't other factors at play. What is making some Greens fail where others last "forever" under what guys are decribing as mild to severe abuse and or "spirited driving", and what would make a tapered bearing fail under conditions that they were made for? Poor fit up?, Is the supplier of the Greens the same each time? Maybe they have a defective batch. I'm hoping to change these bearings once. The stock ones lasted 102,000 in 34 years and failed only because they went swimming for three days and then sat to dry in time I'm a 53 year old kid I plan to do some spirited driving myself but I don't want the first thing my grandaughter has to do to is is changer axle bearings. Like I said, I'm still torn.
