Problems with FCA on a new truck warranty.

U could drive it awhile longer to see if it gets worse. Do u honestly think the techs they have now can set the diff up properly? They will probably have to change the whole rear diff assambly. They won’t want to have to do that. I used to work for a shop that has an auto body with it. The 1s with bent rear housing I changed to new, used the old gears over never once changed the pinion shim, even though the pattern showed it needed changed. No noise ever. I was told the housings were so accurate that it was a bolt in and go. Now don’t get me wrong, the pattern wasn’t corrected cause I was lazy, it was because I was told to leave it alone. If there was a problem they would certainly come back. That was the bosses theory. I no longer work there. Kim
