+1 Bearing fail - All of them can - There is no such thing as 100% quality assurance
The bearing could have been defective
The retrofit INSTALL may not have been smooth - Does anyone know?
The original bearing was replaced so there is some Un-Known history related to the IMSB

Self serving - valid point

porsche-land - if it quacks like a duck and it walks like a duck...
- Your OP is a shot at the LN bearing, that's pretty clear and I think you will get what you want here - a whole lot of threads
Can you hear all those keyboards typing away
If your products are good and prove themselves over time then others will start coming after you

Jack's point - Defending his products, a pat on the back - OK - natural pride in his work.
But one thing that is very clear (at least to me) - I see a lot of posts from Jack offering suggestions, advise and sharing his experiences and knowledge to average Joes such as my self that I don't see as being Self serving, just helping this community

just my 5 cents (accounting for inflation)
