¿Es necesario alinear una cremallera de dirección y una barra de dirección después de reemplazarlas?
Con un instrumento de alineación de cuatro ruedas específico, el técnico medirá el ángulo de convergencia, el ángulo de inclinación y otros parámetros geométricos de la rueda actual. Estos datos se compararán con los parámetros originales del vehículo para determinar el rango y los elementos que deben ajustarse.Ajuste el sistema de dirección y el sistema de suspensión. En función de los resultados de la medición, el técnico ajustará gradualmente los parámetros geométricos de la rueda al estado ideal ajustando la barra de dirección, los pernos excéntricos del sistema de suspensión, etc. Por lo general, el técnico comenzará con la rueda delantera y luego ajustará la rueda trasera según sea necesario.
Volver a medir y calibrar
Una vez finalizado el ajuste, el técnico utilizará el instrumento para medir nuevamente los parámetros geométricos de la rueda a fin de garantizar que todos los valores se encuentren dentro del rango especificado. Si algunos parámetros aún no cumplen con los requisitos, será necesario realizar ajustes adicionales hasta que todos los datos cumplan con los estándares.
Inspección y prueba final
Después de completar la alineación de las cuatro ruedas, el técnico también realizará una inspección final de todo el sistema de dirección y el sistema de suspensión, y realizará una prueba de carretera para garantizar que el manejo y la estabilidad del vehículo vuelvan a la normalidad.
¿Cuáles son las consecuencias de ignorar la alineación de las cuatro ruedas?
Aunque la alineación de las cuatro ruedas es una operación vital, algunos propietarios de vehículos o técnicos de mantenimiento pueden ignorar este proceso por razones de tiempo o de costo. Sin embargo, este tipo de enfoque puede traer una serie de consecuencias negativas:
1. Mala estabilidad en la conducción:
Si los parámetros geométricos de las ruedas no están ajustados en su lugar, el vehículo puede presentar problemas como desviación y fallo de la dirección al circular a altas velocidades, aumentando la peligrosidad de la conducción.
2. Desgaste rápido de los neumáticos:
Los vehículos que no han sido sometidos a una alineación de las cuatro ruedas a menudo presentan un desgaste desigual de los neumáticos, lo que no solo acorta la vida útil de los neumáticos, sino que también puede provocar un aumento de la vibración cuando el vehículo está en marcha, lo que afecta la comodidad de conducción.
3. Aumento del consumo energético del vehículo:
Una alineación incorrecta de las ruedas puede aumentar la resistencia del vehículo durante la conducción, aumentando así el consumo de combustible y aumentando el coste de uso del vehículo.

Effect of wheel alignment
Wheel alignment refers to the geometric relationship between the wheel and the longitudinal axis of the vehicle, which directly affects the balance, handling and tire wear of the vehicle when turning. The adjustment of the steering rack and tie rod has a direct impact on the wheel alignment, because the size and installation position of these components determine the steering angle and inclination of the wheel.
If the wheel alignment is not accurate, it may cause the vehicle to deviate from the straight line while driving, or even over- or under-steer when turning. To avoid this, the wheel alignment must be calibrated after replacing these steering components.
Effect of steering angle
The length and installation position of the steering rack and tie rod directly determine the steering angle of the wheel. When replacing these components, a small error in the steering angle may cause the vehicle to be unresponsive when turning or unstable on a curve. If the steering angle is not adjusted accurately, the handling performance of the vehicle while driving will be negatively affected, increasing the difficulty and risk of driving.
Why is alignment necessary after replacing the steering rack and tie rod?
After replacing the steering rack and tie rod, the geometric parameters of the vehicle have changed. Since the steering system and suspension system are closely connected, these changes not only affect the steering accuracy, but may also cause problems such as increased tire wear, unstable steering, and poor driving experience. Four-wheel alignment (i.e. alignment) is the process of accurately adjusting the geometric parameters of the wheels to return them to the original factory settings or close to the ideal state. The following are several main reasons why four-wheel alignment is necessary.
Ensure driving safety
After replacing the steering rack and tie rod, the vehicle's handling may change significantly, especially when driving at high speeds or making sharp turns. If the parameters such as the toe angle and tilt angle of the wheel are not calibrated, the vehicle is prone to oversteering or understeering in these situations, increasing the risk of loss of control. Therefore, timely four-wheel alignment can ensure that the geometric relationship between the steering system and the suspension system meets safety standards and reduce the possibility of accidents.
Prevent abnormal tire wear
Incorrect wheel alignment can cause uneven wear of the tires and even greatly shorten the service life of the tires. For example, if the toe angle is inaccurate, the inner or outer side of the tire may be under too much pressure when the vehicle is driving in a straight line, resulting in asymmetric wear. Excessively worn tires not only reduce driving comfort, but also increase the risk of tire blowouts. Four-wheel alignment ensures that the tires are evenly stressed during driving, thereby extending tire life.
Improve driving experience
Accurate four-wheel alignment can significantly improve the driving experience. When the wheel geometry parameters are precisely adjusted, the stability and responsiveness of the vehicle while driving will be improved. The steering wheel feedback is more sensitive and the steering is more precise, thereby improving driving safety and comfort. For car owners, a better driving experience not only increases driving pleasure, but also reduces fatigue from long-term driving.
Maintain the stability of vehicle performance
The design of the car has undergone complex calculations and experiments to ensure its stability and handling under various road conditions. After replacing the steering rack and tie rods, if the wheel alignment adjustment is not performed, the performance of the vehicle may deviate, affecting its performance on different road surfaces. Four-wheel alignment can restore the vehicle to a state close to the original design, thereby maintaining the stability of its overall performance.
What are the basic steps of four-wheel alignment?
Performing a four-wheel alignment after replacing the steering rack and tie rods is a technically demanding operation. It requires not only precise equipment, but also experienced technicians to measure and adjust the vehicle. The following are the general steps for four-wheel alignment:
Preliminary inspection
First, the technician will conduct a preliminary inspection of the vehicle to confirm that the replaced parts have been installed correctly and that other parts (such as the suspension system, wheels, etc.) are not damaged or worn. At this time, the tire pressure will also be checked to see if it is normal, because incorrect air pressure will affect the accuracy of the four-wheel alignment.
Measure the current geometric parameters
Using a dedicated four-wheel alignment instrument, the technician will measure the toe angle, camber angle and other geometric parameters of the current wheel. These data will be compared with the original parameters of the vehicle to determine the range and items that need to be adjusted.
Adjust the steering system and suspension system
Based on the measurement results, the technician will gradually adjust the geometric parameters of the wheel to the ideal state by adjusting the tie rod, the eccentric bolts of the suspension system, etc. Usually, the technician will start with the front wheel and then adjust the rear wheel as needed.
Remeasure and calibrate
After completing the adjustment, the technician will use the instrument to measure the geometric parameters of the wheel again to ensure that all values are within the specified range. If some parameters still do not meet the requirements, further fine-tuning is required until all data meet the standards.
Final inspection and testing
After completing the four-wheel alignment, the technician will also conduct a final inspection of the entire steering system and suspension system, and conduct a road test to ensure that the vehicle's handling and stability return to normal.
What are the consequences of ignoring four-wheel alignment?
Although four-wheel alignment is a vital operation, some car owners or maintenance technicians may ignore this process due to time or cost reasons. However, such an approach may bring a series of negative consequences:
1. Poor driving stability: If the geometric parameters of the wheels are not adjusted in place, the vehicle may have problems such as deviation and steering failure when driving at high speeds, increasing the danger of driving.
2. Rapid tire wear: Vehicles that have not undergone four-wheel alignment often have uneven tire wear, which not only shortens the tire life, but also may cause increased vibration when the vehicle is driving, affecting driving comfort.
3. Increased vehicle energy consumption: Improper wheel alignment may increase the resistance of the vehicle when driving, thereby increasing fuel consumption and increasing the cost of using the vehicle.
