Chassis components-From the point of view of use, chassis components are actually more prone to problems than engines, but in routine maintenance, many people often overlook the inspection of chassis components. The parts that are prone to failure of the chassis are mainly concentrated in:
1. Shock absorber: Oil leakage is a precursor to shock absorber damage. In addition, bumps on bad roads are significantly intensified or the braking distance becomes longer. It is also a symptom of shock absorber damage.
2. Suspension control arm rubber sleeve: After the rubber sleeve is damaged, the vehicle will run away, sway, and other failures, even if the four-wheel alignment is not helpful. If the chassis is carefully inspected, damage to the rubber sleeve is easy to spot.
3. Steering tie rod: The loosening of the steering tie rod is a serious safety hazard. Therefore, it is important to carefully check this part during routine maintenance. The method is very simple: hold the lever and shake it vigorously. If there is no shaking, everything is normal, otherwise, the ball joint or the lever assembly should be replaced.
4. Exhaust pipe: The exhaust pipe is one of the most easily damaged parts of the bottom of the car. Don't forget to take a look during maintenance. Especially the exhaust pipe with three-way catalyst should be carefully checked.
5. Universal joint dustproof sleeve: Don't underestimate the dustproof sleeve outside the universal joint. It not only has the dustproof function, but also prevents the grease around the universal joint from losing. Once the dustproof sleeve is damaged, the grease will be very fast. It will be lost, and the universal joint is easily damaged due to dry grinding.
Tires-pay attention to changing the tires regularly. A group of tires is durable and cannot be used for a lifetime. Some people work easily. The frequency of use of the car is relatively low. After using a group of tires for several years, the tread pattern surface is intact. However, in fact, the performance of the tire will gradually deteriorate with the increase of the age, and the quality will gradually decrease. If you don't realize this, thinking that "the surface looks good" means that the tire is okay. That is a wrong view.
When maintaining the tire, first remove the stones and other inclusions in the tire tread, check the tire for blisters, layers, cracks, tarnishing, and aging. Second, when disassembling the tire, remove the rust from the rim and check the inner tube and liner With no damage or wrinkles, inflate according to the prescribed air pressure, and carry out tire flanging or transposition. In addition, check whether there is any friction between the tire and the wing, the floor of the trunk, the leaf spring, the fender, etc.
Battery-The battery is the key to the electrical system. In automobiles, a large number of electrical devices are used. The abnormal operation of the battery will affect the performance of many devices. For example, in an automatic transmission car, if the battery is abnormal, it will prevent the car from starting. Therefore, a stable power supply must always be available.
