The misalignment of the steering wheel is primarily related to tire pressure, tire wear, wear of various chassis components, and wheel alignment. You can start by checking the tire pressure on both sides from the outside; when there's a significant pressure difference between the two sides, the vehicle tends to drift towards the side with the lower pressure. Moreover, if the front tire tread wear is inconsistent, it can also lead to drifting. If there's no evident issue from an external inspection, a detailed check-up at a repair shop is recommended.
Minor deviations in the steering wheel often arise due to the deformation of the front shock absorber springs, leading to inconsistent damping on both sides, or the complete failure of the shock absorber, which causes the vehicle to drift due to uneven suspension heights and forces. The condition of the steering system also impacts the vehicle's linear motion; excessive wear and clearance in connecting components, or wear in bearings, spindles, and bushings can cause the vehicle to sway from side to side, making it difficult to maintain a straight path.
A more severe misalignment is typically caused by the bending or deformation of the steering knuckle or tie rod, leading to significant one-sided drift. Severe wear or detachment of the tie rod ball joint due to wear can also result in steering failure, possibly causing the vehicle to lose control entirely. Therefore, during daily driving, if any misalignment or other issues are noticed with the steering wheel, it's advised to get it inspected and repaired promptly to avoid significant safety risks.
