2018 Ram 2500 Cummins, only 13k miles. When driving I get a a high pitch whine that changes with transmission shifts. I also get the noise at idle when I press hard on the brakes. Little to no noise when idle. Looking online it seems it might be the hyrdaboost and power steering, but the noise is not quite the same. Any ideas, and is it safe to tow my travel trailer home.
