The most easily damaged parts of the car

The most easily damaged parts of cars are: 1. Air filter, 2. Oil filter, 3. Gasoline filter, 4. Air conditioning filter, 5. Engine drive belt, 6. Distributor contact switch, 7. spark plugs, 8. brake pads, 9.fuses, 10. light bulbs, 11. wiper blades, etc.

Various connectors in the electrical part

Except for a very few important electrical connectors on the car that use gold contacts, most of the other connectors are made of copper-zinc alloy. Under normal circumstances, its reliability is guaranteed, but if the car is exposed to high temperature and high humidity for a long time Running in a bumpy environment, these joints may have loose, rusted, poor contact and other faults, and some electrical faults are mostly caused by this. Therefore, during routine maintenance, you should focus on checking the connectors of the computer, sensors, fuel injectors and other components on the car.

Chassis parts

From the point of view of use, chassis components are actually more prone to problems than engines, but during routine maintenance, many people often ignore the inspection of chassis components. The parts of the chassis that are prone to failure are mainly concentrated in:

1. Shock absorber: Oil leakage is a harbinger of damage to the shock absorber. In addition, the obvious aggravation of driving bumps on bad roads or longer braking distances are also signs of damage to the shock absorber.

2. Suspension control arm rubber sleeve: After the rubber sleeve is damaged, the vehicle will have a series of failures such as deviation and swing, even if the four-wheel alignment is not helpful. Rubber boot damage is easy to spot if you inspect the chassis carefully.

3. Steering rod: Loose steering rod is a serious safety hazard. Therefore, it is necessary to check this part carefully during routine maintenance. The method is very simple: hold the tie rod and shake it vigorously. If there is no shaking, everything is normal. Otherwise, the ball head or the tie rod assembly should be replaced.

4. Exhaust pipe: The exhaust pipe is one of the most easily damaged parts at the bottom of the vehicle. Don't forget to take a look at it during maintenance. Especially the exhaust pipe with three-way catalytic converter should be carefully checked.

5. Universal joint dust cover: Don't underestimate the dust cover outside the universal joint. It not only has a dustproof effect, but also prevents the loss of grease around the universal joint. Once the dust cover is damaged, the grease will quickly It will drain, and the gimbal is easily damaged due to dry grinding. tire

6.Wheel: Pay attention to changing the tires regularly. No matter how durable a set of tires is, it cannot be used for a lifetime. Some people work easily and the frequency of use of the car is low. The performance of tires will also gradually age with the increase of age, and the quality will gradually decrease. If you do not understand this, it is a mistake to think that "the surface looks good" means that the tires are fine.
