Wheel alignment eccentric bolts do not cause any harm to the vehicle. Here is more relevant information: 1. Function of wheel alignment eccentric bolts: The wheels of a car have alignment data, and they are not simply perpendicular to the ground. The front wheels have camber and toe angles, and the rear wheels also have camber angles. The wheel alignment data of a car needs to be adjusted regularly because driving on bumpy roads or over speed bumps can cause these data to change. 2. Hazards of incorrect wheel alignment data: If the wheel alignment data is incorrect, it can affect the vehicle's driving stability and handling. Therefore, if issues arise, car owners should promptly perform a wheel alignment. When getting a wheel alignment, car owners can also adjust the alignment data based on their driving habits and road conditions. During daily use, it is important to slow down when driving over speed bumps or bumpy roads.

That eccentric bolt is quite common for adjusting suspension system angles, but it has several drawbacks. First, they're designed to rotate for fine-tuning positions. If made of poor-quality materials or improperly installed, they can easily loosen and shift, causing wheel alignment parameters to deviate. This leads to rapid and uneven tire wear, steering wheel vibrations, or pulling while driving, increasing safety risks. Over time, the bolt itself may deform or corrode, requiring more frequent repairs. Moreover, adjustments demand professional equipment—DIY attempts often result in errors and extra costs, unlike the stability of factory-fixed bolts. We recommend avoiding cheap knockoffs and opting for regular alignment checks at authorized shops.

I have experience with vehicle alignment, and the main issue with eccentric bolts is their unstable parameters. If not tightened properly after installation, the bolts can loosen due to vibrations, causing angle changes that accelerate tire wear and degrade handling. This places a heavy burden on the suspension system, potentially accelerating component aging and increasing maintenance costs. Safety is even more critical—parameter deviations can make the vehicle harder to control during sharp turns or on slippery roads, significantly raising the risk of accidents. To avoid these issues, it's best to choose high-quality bolts and realign the wheels after every tire change.

The use of eccentric bolts causes the rear tires to wear out too quickly, requiring replacement in less than half a year, which is costly. The inaccurate alignment affects the driving experience, as the car tends to pull to one side. The mechanic said it's due to the bolt design issue, making adjustments imprecise and prone to failure. This is a big hit to the wallet and also poses safety hazards.
