Hi All, I am in St. Louis, Missouri and I own a 2019 Ram 1500 Big Horn Sport. I bought it in February of this year 2019. I went on the forum to find some help as my truck, which had 20 miles on it when I drove it off the lot and has less than 2500 miles on it, is making this kind of roaring noise. At first, it happened on a 2.5 hour trip, 3/4 of the way there, at about 60-68 miles per hour. Seems like it makes the noise on a coast, well then it did. Then just recently on city driving it was making the noise on acceleration and de-acceleration driving about 30-35 miles per hour or under. I read some of your posts about the same thing but never really found the solution or the cause. Truck is in the shop. We shall see. Oh and by the way, thanks for the add.
