Yet even my rudimentry mathamatics equate this ratio of 3 in 4,000 installs to a miniscule percentage of failures!! A hell of a lot better than the original.
You guys have more chance of flying to the moon than having a LN bearing failure .......
zzzzzzz I sleep (more than) OK after my install nearly 2 years ago !!!! zzzzz
Most of the 4,000 LN bearings are still relatively new and have low miles (as a population in comparision to the >200,00 Boxsters built over the cars 12 year history with a bearing issue).

All failure trends start small. The question is what the trend does as the part ages and wears.

Hence, my question about the age and number of miles on the three failed bearings. Were they some of the earliest bearings sold? Do they have the most miles? Were the cars driven hard or easy? Manual or tip? Or do these failures appear to be somewhat randomly distributed in age and miles like the OEM bearing?

Inquiring minds want to know...
