I am having trouble diagnosing a problem. When I bought the ATV I was told it might need axle. When you put it in gear it makes a clunking noise then it will drive. However it feels like something is broken. I didn't drive it fast. My cousin says it's probably a rear CV axle???? I bought it for 300$ and it didn't run. I bought battery and cleaned contacts on cylinoid. Need help with this problem so I can ride
