Seems like to me they need to save the t/case, and front diff. But completely adjust the front diff and pinon angle. Still what a big job for dealers, all of which may not have a certified welder. In the end the liability could mean a new front end completely, but that would be even more expensive. I really don't see an option beyond this, and since they are still cranking them out, they need to solve this on the assembly line to stop the bleeding asap. They of course claim dana screwed up the design, but this will become a war of lawyers in court with no real winner I am afraid. They might keep this under 200M, a chunk of change, but manageable. When I get mine back I will start mine own NHTSA complaint, since I don't have the drive shaft here and cant take photos. If we get a couple of dozen to file a complaint things may happen. It does not take many serious safety complaints. We have to emphasize that most will fail after day to day use, and how the danger from a driveshaft coming apart on the highway could lead to injury, and that for most of us we discovered it driving and had to pull over. Ineos will check the under 1% box when replying. But NHTSA knows that will always be the response.
Oh, save receipts for those that have to replace their own shaft like me!
