As a means of transportation, although the price of a car is becoming more and more close to public opinion, a series of related costs after buying it have become more and more unbearable. Puzzled. It is true that any product will cause loss in the process of use. Although the service life of the car is not short, if there are frequent problems with the parts, it will also affect the use of the final car, so the car owner sometimes goes to the 4S shop to repair and replace the parts. Expenses and labor costs become a head-scratcher.
In fact, the parts of each important component of the car also have a certain service life. Take the engine assembly as an example, the timing belt (tape) needs to be replaced every 50,000 to 60,000 kilometers, and the transmission V-belt is every 40,000 kilometers. It is replaced once per kilometer; and some unnecessary replacement parts also need to be checked and cleaned regularly. For example, the distributor contacts are cleaned and checked every 40,000 yuan, and the labor cost required for inspection and cleaning is also one of the maintenance costs that cause headaches for car owners.
However, although maintaining a car is becoming more and more worry-free now, economical and efficient maintenance methods do not exist. Take the chassis components that are most prone to problems. Knowing the early signs of failure can well avoid causing more serious problems. condition:
From the point of view of use, chassis components are actually more prone to problems than engines, but during routine maintenance, many people tend to 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 shock absorber damage. In addition, significantly increased bumps or longer braking distances on bad roads are also signs of shock absorber damage.
2. Suspension control arm rubber sleeve: After the rubber sleeve is damaged, a series of failures such as deviation and swing will occur in the vehicle, and even four-wheel alignment will not help. Damage to the rubber boot is easy to spot if you inspect the chassis carefully.
3. Steering rod: The loosening of the steering rod is a serious safety hazard. Therefore, this part must be carefully checked during routine maintenance. The method is simple: hold the lever and shake it vigorously, if there is no shaking, it means everything is normal, otherwise, the ball head or lever assembly should be replaced.
4. Exhaust pipe: The exhaust pipe is one of the most easily damaged parts on the bottom of the car. Don't forget to take a look at it during maintenance. Especially the exhaust pipe with three-way catalytic converter should be checked carefully.
Jiahang aluminum alloy forging said that in addition, the maintenance of tires does not have to be done in a 4S shop. First, remove the stones and other inclusions in the tire tread, and check whether the tire has bubbling, layers, cracks, deformation, aging, etc. Second, when disassembling the tire, remove rust on the rim, check the inner tube and lining for no damage or wrinkle, inflate the tire according to the specified air pressure, and perform tire flanging or transposition. In addition, check whether there is friction between the tires and the wings, the floor of the car box, the leaf springs, the fenders, etc.
