my name is Ron, I have a 2014 Titan S crew cab, I bought it with 8000 miles, I now have 46,000 miles, the rear differential has started squeeling, and it sounds like its on the right side, I suspect a axle bearing. I am unsure if the drivetrain warranty will cover repairs to the differential, and I am around 80 miles from the nearest Nissan dealer. If the warranty covers these repairs does anyone here know if there is a rental car program in the drivetrain warranty? I dont know where to find out the answers to my questions so I thought I would try here. thanks, Ron.
