The suspension, which is an important part of a car, deteriorates year by year. If you feel the ride is getting worse, the steering wheel swings, or you are worried about uneven wear on the tires, it may be due to the deterioration of the suspension.
Suspension role and the purpose of the exchange
Suspension is an important part that supports the suspension of the car. Installed between the body and the tires, it absorbs vibrations and shocks transmitted from the road surface through the tires, contributing to a comfortable ride, and maintains the tire’s ability to follow the road surface to ensure steering stability. Is the main role.
The suspension also plays a role in supporting the weight of the car. Thanks to the work of the spring, which is a part of the suspension, the car can keep its height.
The purpose of replacing a suspension is to:
Improve ride comfort
The first reason for replacing the suspension is to improve the ride comfort. If the suspension is too hard, it will not be able to absorb shocks and the ride will be poor. In such a case, it is necessary to change the spring or change the damping force of the shock absorber.
Improved steering stability and operability
On the other hand, if the suspension is too soft, the driving stability may be affected, such as the vehicle being unstable, or the responsiveness of the tires to the steering operation may be reduced. In this case as well as improving the ride comfort, you will have to replace the spring or adjust the damping force of the shock absorber.
Lower height to increase stylishness
Suspensions are sometimes replaced not because of functional issues such as ride comfort or maneuverability. If you replace the suspension and lower the vehicle height, you can expect a dress-up effect that will give you a powerful look.
Suspension replacement timing
Deterioration of the suspension will not only reduce ride comfort, wobble the vehicle while driving, but also cause uneven wear of the tires and distortion of the vehicle.
Keeping running with a degraded suspension poses a danger not only to the suspension but also to the entire vehicle, so be sure to replace it if you feel it has deteriorated.
The suspension is roughly divided into three parts: shock absorber, spring, rubber and bush.
The life of each of these components is different and depends on the driving environment and driving style. The guideline for replacement is about 40,000 km of shock absorber, about 100,000 km of spring, and about 80,000 km of rubber bush.
In addition to the distance traveled, there are other ways to judge the deterioration of the suspension, such as the feeling of unprecedented impact, such as reduced ride comfort of the car, rattling, jagged noise, the steering wheel being shaken, etc. It’s a good idea to think that the suspension may be deteriorating.
Also, even if you do not feel such symptoms, it can be said that about 10 years from the registration of the new car is the limit of the useful life of the suspension, so cars that have passed 10 years since the registration of the new car should be checked by an expert.
