Why Doesn't the Car Go Straight When You Let Go of the Steering Wheel?
4 Answers
This situation may be caused by the wheels needing a four-wheel alignment, resulting in the car not being able to drive straight and frequently veering off course. It is best to get it checked. The functions of the steering wheel: 1. For multifunction steering wheels: They can control some functions of the central console, such as adjusting the air conditioning and playing music. 2. Warning function: When the car is in motion, if the steering wheel shows any abnormalities, it indicates a fault in a certain part of the car, so caution is needed while driving. 3. Direction control: The primary function of the steering wheel is to control the direction of the car and manage the internal steering wheels. More related information is as follows: 1. Single-spoke steering wheel: Single-spoke steering wheels were widely used in early vehicles. The inner diameter space of single-spoke steering wheels was very convenient compared to modern ones, but with the application of power steering, the single-spoke steering wheel ended its historical mission. 2. Dual-spoke steering wheel: Dual-spoke steering wheels were also used in early vehicles, but due to difficulties in supporting and installing airbags, the use of this component has significantly decreased.
Last time I drove my friend's old car, I noticed this issue - the steering wheel would pull slightly to the right when loosened, making my arms particularly sore. Actually, steering wheel misalignment is quite common. First, check the tire pressure difference between both sides - if it's 2.3 on the left and 2.6 on the right, it'll definitely cause pulling. Experienced drivers know that messed-up wheel alignment data is the worst - incorrect toe angle or kingpin inclination deviation means the wheels are essentially walking sideways. Another possibility is aged chassis components - loose steering tie rod ends or cracked lower arm bushings (you'll hear clunking noises over bumps) need replacement. Don't force it when this happens - get to a repair shop for alignment machine diagnostics immediately.
When our neighbor Sister Li first learned to drive, she always complained about the car pulling to one side, which scared her into gripping the steering wheel tightly the entire time. Later, it was discovered that her husband often scraped the right curb while parking, causing the wheel rim to deform and resulting in uneven tire wear. Daily driving requires attention to whether the suspension has suffered any impacts. Once, I hit the subframe while driving over a bump, and even a slight bend in the tie rod can cause the car to pull. During a road test, you can intentionally let go of the steering wheel to observe the degree of deviation, but make sure to do this in a safe area. I remember one time after getting a tire repaired, I didn’t get a wheel balance, and the steering wheel shook like a vibrating phone. Never ignore alignment issues—regular tire rotations can help detect abnormal wear early.
An owner who has experienced three alignment issues tells you: The most common cause is tire pressure problems, especially noticeable during significant temperature differences between winter and summer. If the four-wheel alignment data deviates beyond the manufacturer's standard values, the steering wheel will fight you. Worn chassis components can cause looseness, and a clunking sound when turning must be taken seriously. When the steering gear leaks oil or sticks, the steering feels rough, often accompanied by unusual noises. It's recommended to check tire pressure monthly and perform alignment checks every 20,000 kilometers. Sudden alignment issues should be taken seriously—I once had one caused by a stuck brake caliper creating uneven resistance.
