The rear differential splits torque between the two rear wheels while letting them turn at different speeds through a corner. On the high output Charger and Challenger cars it lives a hard life, and a whine that changes with load or a clunk on throttle transition usually means the gears or bearings are done. This genuine Mopar assembly replaces the complete unit rather than attempting a rebuild.
