NHTSA Complaint #11428190 — 2016 RAM 1500

When I bought the vehicle last year it was brought to my attention that something was loose in my front end that shouldn't be by a mechanic and it had only 75000 miles on it then . He had said it could lock up and cause a accident. My truck had been to the dealer I bought it at twice for part on the axel that was leaking some grease. I was told they are wear and tare parts, but they didn't say anything about it seeming loose . I went for inspection and I was told that I need a new front end axel assembly kit that is 3000$ and they took my inspection sticker for it saying it is unsafe to drive until fixed that it could lock up and cause a accident. This sounded just like what the guy told me at 75000 miles. I was told it was bad at the dealer I bought it from at the time of inspection and when I looked up online it said the milage it is good for 80000 to 100000 miles. There has been no warning and I did not notice a problem so I went to a mini mechanic he gave me a sticker but I am noticing the axel being bad now. I am scared to drive my vehicle and if this is the case that it goes bad every 80000 to 100000 miles shouldn't it be recalled? The mini mechanic told me dodge did not design the axel to be protected from dabre and to keep it in better condition to take it off and grease it every once in a while. Yes my truck is available for inspection upon request . Thank you would like a clear answer on this soon where I have a child that I don't want to have put in danger or those around me.
