2. The shop that did the installation, they said that they had the LN kit failing after only 20k KM (12500 miles), hence they won't warrant the work on IMS. Has anyone had, or have heard of the LN part failing?
Thanks!

While the dual row is a decidedly better performer than the single rows, they also suffer failures, just not in as large numbers.
There have been a handful of documented LN failures, but most were due to poor installations rather than the bearings themselves, or contamination by the failure of a non related engine component. There have also been "stories" about problems with the LN kits, but these came from a source that was openly promoting a different replacement, so a grain of salt is in order. At the end of the day, LN has 20K+ successful installs running around, so their reputation is not in doubt.
