Why does my car pull to one side? | The 4 Most Common Reasons

05
Jan

When driving, steering usually requires little effort—just a slight correction here or there to keep the car on course.
However, if you consistently feel the vehicle pulling to one side while driving, or if you feel like your arms have just completed a heavy workout when you step out of the car, it's time to seriously check if something is wrong with your vehicle.
In addition to the annoying sensation of a hard-to-turn steering wheel, a car pulling to the left or right can actually indicate issues with the brakes, tires, or the steering and suspension system. Here are some of the most common causes and inspection methods for a car pulling to one side: 📋🔧

Inspect the front brake calipers / brake pads / brake rotors / brake shoes

If you notice the vehicle pulling to one side when braking, start by performing the following checks:
📋 1. Visually inspect the front brake rotors and drums for hotspots or areas damaged due to overheating.
📋 2. Check whether the brake calipers are functioning correctly and observe their movement within the brackets.
📋 3. Inspect the front brake linings or brake pads for any signs of fluid leakage.

Uneven friction between the left and right front brakes can cause the steering wheel to shake from side to side. If the front brakes appear to be in good condition, check the brake calipers or brake shoes to ensure both are properly adjusted. This ensures that the movement speed and distance of the left and right brake pads or shoes are identical when the brake pedal is pressed.
The braking system is a critical safety component, and any abnormalities should be immediately addressed with necessary repairs to ensure your safety.

Check the Tires for Unusual Wear

If the steering issue isn't related to the brakes, the next step is to inspect the tires. Look for any clues in the front-end steering or suspension. Visually examine the wear pattern on the opposing tires to see if there are any noticeable differences.
Next, observe whether one or both tires have feathered or rough edges on the inner or outer sides; this check can reveal if the wheels are correctly aligned.
However, the absence of tire wear doesn't necessarily guarantee there isn't an underlying issue. Damage to the steering system from impacts or debris can cause the steering wheel to pull to the right or left even before you notice any tire wear.

Inspect the Wheel Bearings

When a wheel bearing fails, it can feel as though an invisible force is pulling your car to one side while driving. The hub, tire, and wheel are the three main components that rely on a properly functioning wheel bearing. The wheel bearing allows the hub assembly to rotate smoothly and move freely.

You can check the wheel bearings without removing the tires to see if they might be the source of the problem. Use a jack to lift the car, and then spin the wheels to listen for any unusual noises. Simultaneously, grab each wheel and try to shake it to see if there is excessive play (bearing clearance). If you hear noise or feel excessive play, a faulty wheel bearing might be the cause. It's recommended to have a professional technician diagnose the issue.

Check the Steering Links, Ball Joints, and Tie Rod Ends

Worn or weakened components in the vehicle's steering and suspension system can cause the car to drift left or right.
If you look behind the front right or left wheel, you'll see how the wheel is connected to the steering knuckle. Each steering knuckle is linked to the steering and suspension system. Tracing back along the steering gearbox, you'll find a series of links connected to the steering knuckle; similarly, following the steering rack and pinion will also lead you to the steering knuckle. That's why the wear and tear of the steering system is closely related to steering irregularities.

The final connection between the steering gearbox or rack and pinion and the left and right

Steering knuckles is called the tie rod end. Each tie rod end has a ball joint that securely fits into the steering knuckle. The ball joint is a steel component that connects the control arm to the steering knuckle, while the tie rod end is a 90° outward bend. The fit between the tie rod end and the ball joint must be both stable and capable of movement. The clearance between each tie rod and its corresponding ball joint is almost zero, so it's essential to ensure these parts are intact.
