Why Does Your Car Pull to One Side?

In a previous article we’ve talked about the reasons why a vehicle can start vibrating while driving, and why you might feel it in the steering wheel, the pedals or your seat, for example. Another annoying anomaly is when the car doesn’t drive in a straight line or deviates from its trajectory, as if a mysterious force was pulling it to one side of the road.

This phenomenon can have various causes. Here are the main ones:

1. Tire Pressure

If your left and right tires don’t have the same air pressure, especially at the front, it’s very likely that your car will not stay on course and will pull to one side. This is another good reason to check your tires’ pressure regularly, ideally once a month (or more if temperature changes are significant). Warning: over-inflated tires can cause other problems. Stick to the pressure recommended by the vehicle manufacturer.

2. Wheel Alignment

Of course, a vehicle whose four wheels are no longer perfectly parallel due to repeated impacts or damaged suspension/steering components will also tend to pull to one side. If that’s the case, the wheels must be realigned in a mechanical workshop. Once the work is done, take it for a test drive to make sure the problem has been solved.

3. Brakes

Does your car deviate only when you apply the brakes? If so, it’s a sign that they are not working properly. For example, the calipers may not fully release the discs, the discs may be distorted, or the brake lines may be damaged. An inspection of the braking system will make things clearer.

4. Wear

Finally, excessively worn or damaged suspension and steering parts can prevent a vehicle from driving in a straight line. The same goes for wheel bearings that are too old. Generally, you’ll hear unusual noises and feel vibrations in the steering wheel if that’s the case. Don't wait any longer and make an appointment with a repair shop to have your vehicle inspected and the worn parts replaced.
