I've got a 2021 1500 Bighorn 5.7 Quad 2wd that I bought new. At interstate speeds, anywhere from 55-75mph it's developed a strange linear "vibration' as it goes on/off bridges or even striking the odd dip or bump in the road. There's no sound involved in it but the sensation is almost like you're holding a line and whipping it up and down. It lasts for a few seconds then goes away. I've looked all under it thinking I might find a broken exhaust hanger but nothing is apparent. I've wrenched for almost 50 years but this is a new one on me. Hoping someone might have an ifea/solution.
