The front suspension arm is the guiding element of the undercarriage of every modern car. It provides connection and transmission of all forces to the vehicle body.
This part is a device connected at one end to the wheel, and the other end to the body. Thanks to this lever, the vertical movement of the wheels is carried out, as well as the transfer of their forces to the frame.
At the moment, there are several types of such devices:
- Longitudinal front suspension arm.
- Transverse.
- Diagonal.
- Rod.
- Triangular.
Where is it installed?
As a rule, this mechanism is mounted on cars with independent suspension. The fact is that this running system does not have such a connection between the wheels as the dependent one (the wheels are connected using a tin beam, therefore they move autonomously from each other). In our case, the suspension involvesthe presence of various levers connecting the suspended part of the vehicle with the wheels. Thus, all elements are interconnected.
By the way, in the modern world, more and more manufacturers refuse to use dependent suspension, as it does not have such a high degree of reliability as the second one. Therefore, this technology remained only with the domestic auto industry.
And back to the levers. Now many designers are dealing with multi-link schemes that provide ideal tire kinematics, stability and good vehicle handling. One wheel can be equipped with two or even four levers. However, the more elements on one disk, the more complex and expensive the design will be. Therefore, automakers strive to have no more than a pair of such mechanisms per wheel.
When does a car need a front suspension arm replacement?
This element can fail at any moment, therefore, in order to avoid trouble on the road, you should regularly diagnose the specified part for serviceability. Fortunately, you can determine its wear yourself. Moreover, all the work will not take you even five minutes. In order to find out if the front suspension arm is working or not, you should install the arm with a ball joint so that the mandrel of the centering part comes into contact with the end of the hinge pin. After that, you should insert the installation fingers into the extreme and middle holes. If this is done without effort, the front suspension arm is in good condition.condition. If the fingers enter the hole only with force, then the part is deformed and must be replaced. You can go the other way - to repair the old one. In this case, a repair kit with all the necessary parts is purchased and the repair process is carried out.
How much does a car front suspension arm cost?
The price of this device directly depends on the brand of the car. So, the front suspension arm of the VAZ of the “ninth” and “tenth” families costs about six hundred rubles. For an imported Renault, the same part will cost at least 3,000 rubles.
