If you want to know why your trailer sways while driving (fix this), the answer is almost always weight distribution. Sway, or “snaking,” occurs when there is too much weight at the very back of the trailer. This acts like a pendulum, pulling the rear of your car from side to side and potentially causing a rollover.
To fix this, ensure 60% of your load’s weight is in the front half of the trailer. This creates “downward” pressure on the tow ball, which stabilizes the connection. Additionally, check your tire pressures; uneven pressure between the left and right trailer tires can cause the unit to “track” poorly, leading to that terrifying wobble at highway speeds.
