What is the reason for the steering wheel not being straight when the wheels are aligned?

The steering wheel not being straight when the wheels are aligned is due to misaligned gears. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low during that period. Tires can also age from prolonged disuse, so it's important to check the production date when purchasing new tires.

I've encountered the issue of misaligned steering wheel after wheel straightening several times, with improper wheel alignment being the most common cause, such as incorrect toe settings or imbalance. The steering system could also be faulty, like bent tie rods or worn ball joints, especially in older vehicles that have endured rough roads. Suspension system deformation is another potential factor – I once had a case where the steering wheel leaned slightly right, and inspection revealed shock absorber problems. The solution is to visit a professional shop for four-wheel alignment or comprehensive maintenance. Neglecting this accelerates tire wear and affects fuel efficiency. Driving safety is paramount – bi-annual suspension checks can prevent these issues, saving both money and hassle.

When the steering wheel is not straight while the wheels are aligned, it is mostly caused by incorrect wheel alignment, such as inaccurate toe adjustment. Deformation of steering components like tie rods can also cause deviation, similar to how suspension wear affects balance. I feel this issue shouldn't be underestimated—over time, the steering wheel may become increasingly misaligned, leading to accelerated uneven tire wear and reduced handling stability, which increases collision risks. Once, I experienced a similar situation while driving in the rain and had to make an emergency stop to check, fortunately, it was just a minor issue. I recommend regular suspension maintenance and avoiding bumpy roads to minimize such problems.

This issue commonly arises from improper alignment, with toe angle deviation being the most prominent. Defects in the steering system, such as bent tie rods or aged ball joints, can also cause similar symptoms, especially with suspension deformation. I recommend performing a four-wheel alignment correction or checking tire wear uniformity. Timely repairs can prevent safety risks and extend service life.
