That does help me feel better that is is not a lurking issue. I am scheduling for next week to take it to a different shop to have it looked at. The first time at the dealer it took them 3 tries to get it right...Not the LSD. So, let's get that one out of the way. Also, there is no "special balancing" that's required for the N. The reality is more cars are a LOT more sensitive to wheel balancing now than even 10 years ago, as they steer quicker, have a faster off-center response, AND have a generally numb feeling for the driver. I had a '78 Oldsmobile Delta 88 decades ago that had such strong/sensitive power steering and numb road feel, you wouldn't even tell that you've been compensating for the drift to the right. And with high road crowns in most places, that's what they do. It's usually when they veer left that drivers take notice and go back in for an alignment and the tech will try to compensate for the crown if the rest of the alignment and thrust angle check out.
And yes, a poor wheel balancing job will make those 4 lovely gyroscopes fight the base alignment of the car. ;-)
