Flat-towing a car – that is, towing it with all four wheels on the ground, transmission in Neutral – is bad practice unless you know your vehicle was designed for it.
That isn’t necessarily common knowledge, but it’s the truth: pulling a vehicle along, both axles on the ground, turns the wheels. Those wheels turn the half shafts, which transmit torque through the entire drivetrain, including vital transmission components. If the vehicle is an automatic, or if it’s a manual that relies on an engine-driven pump for proper lubrication, those components are spinning and they aren’t getting the lubrication they need, causing accelerated wear.
Why are we telling you all this? It’s setup for what follows: the 2021 Ford Bronco Sport has not been designed for flat-towing.
