Rear Axle Spindle Problems of Nissan Sentra

I don't know if this is a one-time,only-thing, but felt I wanted to mention it. My mother drives a 2010 Nissan Sentra, built about 2/10 it has never been serviced by the dealer except for 'included' oil and filter changes, as part of the new car 'sell' I took the front left wheel off, to rotate the tires and, since I have replaced control arms, and cv axles myself in the past, looked around. The 32 mm spindle nut was loose enough to turn by hand, the original cotter-pin (painted black while the car was built) was original-properly intact. I consulted my technical manual and it said that this 32 mm spindle nut is usually torqued to 92 foot-pounds-not finger tight. In fairness as I write this-to leave no stone unturned-and to the manufacturers defense-the car did hit a curb on that side-and the tire blew-it was replaced by etd tire service in NJ. But that cotter pin is original-never removed. So a socket could not have been put on it to loosen it from the original torque setting. Unless the shock of the tire impact jarred it loose? knocked the wheel bearing and loosened the spindle nut? either way-I am glad I spotted this. I wonder if this torque specification is adequate? 92 foot lbs. ## VIN failed ## 2010 Nissan Sentra sr ##.

Rear tires are wornout @ 11,000 miles. Nissan replaced 2 rear axles and rear suspension assembly and 2 rear tires. They changed the alignment specs and said it was fine. Consumer affairs didn't answer calls for 2 months. Inspector checked the rear tires that had just been rotated from the front and said they didn't show signs out being out of alignment. They wouldn't contact their factory in TN / safety engineer who had requested the original rear tires be shipped to them. A similar vehicle was checked by the dealership and it too had alignment specs that were out and similar to our vehicle. We have 24000 miles and ready for a second set of tires. Still out of alignment, has always been out of alignment, technicians state it'll never be in alignment because there's an engineering problem.
