Hey all, new to these forums so let me know if I posted in the wrong area. Ultimately, I have a '15 1500 and over the course of about 3 weeks I have noticed a strange rattle, or bounce, under the front end while going over small bumps on the road. Specifically right under my feet is where it feels like. I took it to the dealership and they had it all day trying to find it, they said they tightened bolts here and there, and finally came to the conclusion that it was some bracket under some manifold that was bouncing and vibrating after going over bumps. Well a week later and I still feel it, although it isn't as strong, it is definitely still there. So my main question would be, is this just a normal feeling with this truck, and I didn't notice it before? If it's not, where do I begin my search, and what should I look out for? Thank you.
