Looking around for a 3500. Found a '14 with low miles, but it seems to be a buy back truck from California. Steering issues, dealer could not replicate the problem. What changed from '14 to '15 frame/...
If they couldn't replicate the problem then they couldn't see what the problem was. In my experiences with FCA, there is no problem if they can't see it. Even if they can hear or feel it but can't find the source they will call it "normal". Highly doubt they would buy back a truck that didn't at least replicate the problem. There has to be more to it.
