Can anyone help me with this, i have a 2019 Silverado LTZ with 16001 miles on it. When slowing down to come to a stop, there is a loud bang, and you can feel the truck shake coming from under the bed area. However it doesn’t always happen, seems to happen on longer drives as opposed to shorter drives. I’ve had the truck at the dealership, but they weren’t able to replicate the banging, while driving it. Thanks
