Check the amount of oil, throttle opening and closing, gas emissions and other conditions are easy to see, we can check next to the car. However, some components that are critical to our safety and vehicle condition are not easily seen - the chassis of the car. Therefore, the master suggested that the small partners must pay attention to these 4 parts when they are maintaining the 4S shop.
1, the shock absorber does not need to change often but pay attention to the "chassis 4 large parts"
The common problem is oil leakage. Once the leakage shock damping decreases, the vehicle's driving stability and comfort deteriorate. When the road surface is bumpy, the resonance of the vehicle body becomes severe and the braking distance becomes longer.
2, "ball cage"
Do not need to change often but pay attention to the "chassis 4 large items"
The ball cage is also called the universal joint. The ball cage is a layer of rubber sheath that protects. Do not underestimate the rubber sleeve. It not only has dustproof and sealing effect, but also can prevent the loss of grease around the cage. Once the dust jacket is damaged, the grease will soon be lost to dry grinding, which can eventually lead to scrapping of the axles.
3, the wheel bearing does not have to change often but pay attention to the "chassis 4 big pieces"
The reason why the rut can turn, it certainly can not be separated from the bearing, the vehicle is driving every day, the bearings are turning every day, so it is necessary to check the front and rear wheel bearings. The inspection method is also very simple. Raise the vehicle and release the handbrake. Turn the wheels in succession by hand to hear if there is an abnormal sound. If it does not mean that everything is normal.
4, the steering rod does not have to change often but pay attention to the "chassis 4 large items"
The occurrence of looseness in the steering lever is a particularly serious hazard. Therefore, it must be checked during maintenance. The method of inspection is not difficult. Hold the lever and shake it vigorously. If it is not loose, it means that everything is normal. Otherwise, replace the ball or the rod assembly. Check yourself to wear gloves. It's too dirty.
