Is It Serious If the Car Pulls to One Side?

Yes, it is serious as car pulling to one side poses significant safety hazards. Car pulling refers to the phenomenon where, when the car is driving at a constant speed on a flat, straight, dry, and clean cement or asphalt road, releasing the steering wheel causes the car to automatically veer left or right, resulting in the centerline of the front and rear axles not aligning with the centerline of the driving trajectory. The reasons for car pulling include the following: 1. Car pulling caused by tire issues: Uneven tire pressure on the same axle will cause the car to pull toward the side with lower pressure; different tire specifications on the same axle, leading to different wheel diameters, will cause the car to pull toward the side with smaller tires, a phenomenon that may occur after replacing a tire with a non-full-size spare; different tread patterns on the same axle can cause inconsistent tire-to-ground adhesion, also leading to pulling; additionally, some models use unidirectional tires or asymmetric tread tires, and if these tires are not installed in the correct direction, the car may pull while driving. 2. Car pulling caused by steering system faults: If there is a fault in the steering system, the car will inevitably pull, such as excessive gaps in steering linkage ball joints, support arm bushings, stabilizer bar bushings, etc., or excessive clearance in the steering gear rack and pinion, causing looseness in the entire steering system and resulting in car pulling; for models with hydraulic power steering systems, aging or leaking internal seals in the steering gear, or stuck valves can also cause inconsistent steering feel or pulling. 3. Car pulling caused by incorrect wheel alignment: Wheel alignment is crucial chassis data that directly affects the steering wheel alignment, such as caster angle, kingpin inclination, camber angle, toe-in, etc., and for rear-wheel-drive cars, thrust angle, etc. These parameters directly influence the car's steering characteristics. After driving for a period, due to changes in the gaps of various chassis connections, the wheel alignment data may change, leading to car pulling.
Never underestimate vehicle pulling issues. As a driver, unstable steering is my biggest fear. Last time on the highway, my car kept pulling to the right - I had to constantly fight the steering wheel to maintain straight-line driving. After just two hours, my arms were exhausted. I immediately took it to the shop and discovered significant tire pressure imbalance: the right front tire was underinflated, causing uneven wear. A few more days and that tire would have been ruined. My advice: check tire pressure first when noticing pulling. If pressures are equal but pulling persists, a wheel alignment is likely needed. Minor steering system issues left unattended can damage suspension components, potentially leading to costly repairs. Remember: safety first - don't wait for an accident to regret inaction.
As a seasoned driver with ten years of experience, I've encountered multiple instances of vehicle drifting. Simply put, it's caused by uneven wheel force distribution leading to directional deviation. Common causes include abnormal tire pressure, uneven tire wear, brake system sticking, or misaligned wheel positioning. Last time my car drifted, it turned out to be wear on the left front wheel bearing - continuing to drive could have led to steering failure. I recommend testing on a flat straight road: lightly hold the steering wheel with both hands, and if the car consistently drifts more than 1 meter at 80 km/h, immediate repair is necessary. Ignoring this issue is dangerous, increases fuel consumption, and accelerates component wear.
Wheel misalignment isn't fatal but must never be ignored. Once when driving my kid to school, I noticed having to keep the steering wheel tilted - I thought it was just the road surface and didn't pay attention. Two weeks later, the left front tire was completely bald. The mechanic said this was classic uneven wear caused by alignment issues. Self-check recommendations: observe if the steering wheel centers when parked, check for consistent tire pressure. Regular family cars should get wheel alignment every 20,000 km, especially after rough roads or new tire installation. Don't begrudge that hundred-yuan alignment fee - it's cheaper than replacing tires, right? This is one expense you really can't skip.
