Question hi my friends team associated gt2 is running but the tires dont move when the car is on the ground it just rev's but they do move when not on the ground. can you help please
Answer Hi Therin,
It sounds like the rear differential is worn out and slipping. This is pretty common and just requires that the differential be rebuilt with new differential rings and balls and then readjusted to proper working order. It should be fairly inexpensive...probably around $20. Good Luck!
