Q: Engine RPM Oscillates When I Come to a Stop and Thumps When Placed Into Drive
Whenever I place the car into Drive, the car makes a loud thump like a glove hitting a boxing bag. When I come to a stop while in Drive, the engine RPM oscillates as if it's stuck in gear (see link). When I place the car into Neutral, there isn't any oscillation. Now I've just had the transfer case and front differential replaced from a 52,000 mile Grand Cherokee. Occasionally, ill get the "Service 4WD" notice. As a side note, there seems to be a whirring in the front right tire. (https://youtu.be/To_C5S0ZPgg)
