LN engineering doesn't fabricate bearings. They chose an application that applies to this case. The bearing, i pay 300$, if i bough many (more than 4) i would have paid 250$. Now with a machined flange and some research, as a business man, i wouldn't have a problem with selling it 650$.

It is just a motor with an engineering issue. The thing is that because it is written PORSCHE on it, everyone looks at it with big eyes. It's only a bearing #6402DU17 nothing more.
The failure happens on cars that are not driven enough in time and RPM.

An industrial ceramic hybrid bearing greased and sealed for life is the solution. Why to pay 650 ? and to pay 250$ for tools ? The bearing is 300$ that's allready enough. I even believe that this is THE bearing that they use. It took me 30 min to figure out how to make my own tool and 15 more to take out the bearing. I don't need to study the thing for 3 years to get it done properly.

When i get it monday, i will take pictures and post it here to get some insights.

And also, if it works on my engine, i don'T see why it won't work on 100 more. Engine are all designed the same. It's not a lunar exploration with hazardous solar winds. It's a shaft that revs to 7000 rpm in a controlled environment.

Its not that the part used was a poor choice.... it was where they located it, (in the shaft) that was the poor choice...
the oil starts seeping in/out at around 230/240F, at any rpm. Low useage cars have low mileage, its more of a time thing, not mileage
