NHTSA Complaint #11463804 — 2017 RAM 1500

My rear axle is at a ram dealership have the complete rear axle replaced. It has 90,000 mi and a few thousand miles ago it started to emit a whining noise that just continued to get louder the more I drove it. I took it in one week ago and after a tech checked it out I was told that the entire rear axle had to be replaced at a cost to me of over $5600. I opted to have a used axle installed for half the cost. This problem if left could have led to the rear axle locking up and loss of control. In searching the internet I have found that face has had some recalls on different year trucks for loose pinion nuts and low fluid from the factory and lack of proper heat treating of axle and gears leading to failure. Consumer stated old axle will be available for inspection.
