Nissan finished putting a S27A back in my truck today. For 30 miles it was quiet then the whining started again. I was told by Nissan district rep that Nissan engineers would be there to verify all was good. No one showed up and the dealer knew nothing about it. I still think Nissan changed the 07 model diffs but for some reason they will not put one in my truck. I think Dana is giving these old diffs to Nissan for free to replace faulty 04-06 trucks. If nissan puts a 07 in they would have to pay for it. I also noted that the shop foreman installed both my last diffs which is probably free to the dealer since the foremans time is probably spread out to all work orders. I will be getting back to Nissan consumer affairs but I doubt they will do more than B/S. Probably headed for BBB arbitration or lemon law.
