Hello, thanks for writing in about your GMC Yukon. You would first have to determine what caused the gears to break. If the rear end is repairable then get the broken parts replaced. If it’s too damaged then I recommend getting a used rear end from a junk yard and install it. If you need some help with getting this fixed, consider YourMechanic, as one of our mobile technicians can come to you and service your vehicle.
