They say you must have a video how the heck do you video when you are backing up and all of a sudden your wheels lock up gives you such a jolt that your neck feels like its going to come off. This is my third Ram and I never had a problem with them. When it locks up it feels like you hit something. Makes a very loud noise. I took it in to get it check and the mechanic said I can't find nothing wrong. Right it only happens when I start to back out of my driveway which has a little incline. So afraid that this will seize up on a highway and then it will be too late. I need an answer.
