What is the best craft to learn now? What is the most popular technology? For some common sense problems of wearing parts, always pay attention in the car!

1, spark plug

Replacement cycle: 30,000 km

Spark plug directly affects the acceleration performance and fuel consumption performance of the engine. If it is not maintained for a long time, or even replaced on time, it will lead to serious carbon deposition in the engine and abnormal operation of the cylinder. Spark plugs need to be replaced every 30,000 kilometers. When choosing a spark plug, first determine the model and temperature of the car. I feel that the engine power is insufficient when driving, so I need to check and maintain it once.

2. Buffer

Replacement cycle: 654.38+ million kilometers

Oil leakage is a harbinger of shock absorber damage. In addition, it is also a sign of the damage of the shock absorber that the bumps on bad roads are obviously aggravated or the braking distance is longer.

3. Rubber sleeve of suspension control arm

Replacement cycle: 3 years

After the rubber sleeve is damaged, the vehicle will have a series of faults such as deviation and swing, and even four-wheel alignment will not help. If you carefully check the chassis, the damage of the rubber sleeve is easy to find.

4. Steering tie rod

Replacement cycle: 70,000 km

The slack of the tie rod is a serious safety hazard, so the component must be carefully checked during daily maintenance. The method is simple: hold the lever and shake it vigorously. If it doesn't shake, it means everything is normal. Otherwise, replace the ball head or pull rod assembly.

5. Exhaust pipe

Replacement cycle: 70,000 km

The exhaust pipe is one of the most easily damaged parts under the car, so don't forget to take a look at it when overhauling. Especially the exhaust pipe with three-way catalytic converter, we should check it carefully.

6, dust cover

Replacement cycle: 80,000 km

Mostly used in steering mechanism and shock absorption system. These rubber products will age and crack over time, leading to oil leakage, making the steering rough and heavy, and the shock absorption will be ineffective. Pay more attention to inspection at ordinary times. Once damaged, replace it immediately.

7. Ball head

Replacement cycle: 80,000 km

Check the steering rod ball joint and dust cover for 80,000 km, and check the upper and lower control arm ball joints and dust cover for 80,000 km, and replace them if necessary. The steering ball head of a vehicle is similar to the joints of human limbs, and it is often in a rotating state and needs good lubrication. Because it is wrapped in a ball cage, if the grease is deteriorated or defective, the ball head in the ball cage will loosen.
