What to Do When There's a Slight Friction Sound from the Wheels at Low Speed?

It may be due to broken gear teeth or surface damage on the drive wheel. In this case, you should pull over and inspect. If the gear is damaged, it should be replaced promptly. If the car is in the running-in period, the differential planetary gears and the half-shaft gears may not be properly matched, leading to abnormal sounds during this phase. It could also be caused by improper operation, resulting in poor coordination of car parts and thus generating unusual noises.
