Thanks for all the great tips! My motor and gear box is fine, no broken parts. If it's jacked up with the wheels not touching the ground it runs just fine, then when I put it on the ground it doesn't go anywhere?? Any ideas? It's a Ford STX
Either the wire came disconnected from the motor, or the motor is bad. Take it apart and see what's going on. If the motor is bad, you should replace them in pairs. Usually $20 a piece on eBay/Amazon
We just bought a brand new realtree lightning UTV 12 volt and the passenger wheel goes backwards in 4 wheel drive. All the others go forward.. any help would be appreciated
