What causes hard thumping and tire noise when I'm slowing down and speeding up

Hi, I'm one of the auto experts on RepairPal's Car Genius team! On your 2017 Jeep Renegade a hard thumping and tire noise specifically during acceleration and deceleration is a pretty telling symptom. A worn or failing CV axle is one of the most common causes of this type of noise, as the CV joints can develop play and produce a noticeable thump or clunk when load is applied and released. A failing wheel bearing is another strong possibility, as they can produce both a thumping and a roaring noise that changes with vehicle speed and load. It could also be a worn motor mounts or even something with your tires or brakes. Since some of these causes involve components that are important for safe vehicle control we'd recommend having a qualified shop put it on a lift and do a proper inspection sooner rather than later.
