【Car owner's car knowledge]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 4 Replace every 10,000 kilometers; and some unnecessary replacement parts also need to be checked and cleaned regularly. For example, the contacts of the distributor are cleaned and checked every 40,000 kilometers, 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 damage to the shock absorber, 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, the vehicle will have a series of failures such as deviation and swing, 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:Steering rod slack is a serious safety hazard, so be sure to check this area carefully during routine maintenance. The method is simple: hold the lever and shake it vigorously. If there is no shaking, then 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 under the car, so don't forget to take a look when it is overhauled. Especially the exhaust pipe with three-way catalytic converter should be checked carefully.
5. Universal joint dust jacket:Don't underestimate the dust jacket 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 jacket is damaged, the grease will be lost quickly. The knuckles are easily damaged.
