Under what circumstances should the swing arm be changed?
The impact causes deformation of the swing arm or cracks in the swing arm.
If the direction of swing occurs during the driving process, the direction of the left and right weight is different, the brake direction is off, and the swing arm is noisy or abnormal during turbulence, it indicates that the swing arm has been damaged, and it is recommended to replace it as soon as possible.
Note the following points during use:
1, whether rust: If the swing arm is found to be rusty, it must be handled in time to the 4S point to prevent breakage accidents;
2, to avoid chassis rubbing: when passing through the pothole road, to slow down through, to avoid rubbing the chassis, so that the swing arm cracks, swing arm damage will lead to direction shaking, deviation, etc.;
3, timely replacement: the swing arm of various materials has different service life, and should be replaced in time according to the vehicle maintenance manual and the recommendations of the 4S shop;
4, if the swing arm is replaced, four-wheel positioning should be carried out to prevent the car from running off or eating the tire phenomenon.
The main material of swing arm on the market:
Aluminum alloy material: Aluminum alloy material has the characteristics of light weight, high strength, etc., and the toughness of automotive aluminum alloy is very good, which can cooperate with the suspension movement in a better state, but the bottom arm of aluminum alloy material is the most expensive, mainly used in various luxury brands.
Cast iron material: The so-called cast iron is the iron after melting, pouring into the mold to shape a fixed shape. The strength and rigidity of cast iron is second only to that of aluminum alloy, but due to the characteristics of cast iron, the toughness is poor, so you can often see the front suspension of some vehicles directly broken, rather than deformed.
Double-layer stamping parts: Simply put, double-layer stamping parts are 2 steel plates through the stamping of the machine tool to form two independent shape stamping parts, and then the two stamping parts are welded together, the strength is not as good as cast iron, toughness is better, but it will be stressed and deformed when it encounters a strong impact.
Single-layer stamping parts: As the name suggests, there is only 1 piece of stamping parts, not like bilateral stamping parts through welding.
