It is normal for new car glass production dates to differ. "Because car glass is typically produced by other factories and then transported to the assembly workshop for assembly, the production dates must vary depending on the batch of glass produced by the car glass factory.". "Glass spare parts will be prepared some time in advance, and there is no guarantee that they will be assembled immediately each time. Therefore, it is normal for glass production dates to differ somewhat from each other.".

Identify whether the car glass has been replaced:

1. Looking at the glass label, in most cases, after the replacement of automotive glass, the label on the new glass will be significantly different from the original glass. Generally, the original glass label not only has the identification of the automobile brand, but also has the identification of the glass brand.

2. According to the production date, under normal circumstances, the production date of the entire vehicle glass is close to the production date of the entire vehicle. If there is a significant difference between the production date of one glass and the other glass, it indicates that the glass has been replaced.

3. Look at the manufacturer. By looking at the manufacturer's code number on the glass, you can see which manufacturer the glass comes from. Generally, automobile manufacturers purchase glass in batches, and do not use too many brands or different origins of the same brand.

Generally speaking, there is no accurate standard for how often the cage should be replaced, but if the cage is broken, it should be replaced at any time, as this affects the normal use of the entire vehicle transmission system.

The automobile ball cage is divided into an inner ball cage and an outer ball cage, also known as a "constant velocity universal joint.". The main function of the ball cage sleeve is to prevent dust from entering the ball cage and prevent lubricant loss within the ball cage. Damaged shafts can cause dry grinding, and in severe cases, they can lead to scrapping of the axle shafts. Therefore, routine inspections must be carried out. So the question arises, why do cars always have bad outer cages?

In fact, the outer ball cage of the front wheel of a car is still very durable under normal lubrication. The manifestation of damage is generally excessive wear. There are two reasons for excessive wear. The ball cage sleeve is missing and the seal is not tight. The main reason is that the rubber protective sleeve is damaged. Once the rubber protective sleeve of the ball cage is damaged, within three months, the ball cage will be scrapped.

Ball cage accessories are actually inexpensive and have similar durability. The difference lies in the rubber protective sleeve. The service life of the car ball cage universal joint basically depends on the service life of the protective sleeve. The service life of the ball cage sleeve also depends on the process and material, and ultimately will be reflected in the price. Therefore, it is important not to try to buy accessories cheaply, otherwise it will only be you who have to worry in the end.

The ball cage protective covers of automobiles are generally relatively durable. Once damaged, the repaired ball cage protective covers typically have a service life of 2 to 3 years. If the original ball cage is damaged, cracks may appear in about a year. If you buy a non original accessory, it is recommended to inspect the ball cage within three months. Generally, the ball cage can be seen from the top to the bottom by opening the engine cover.

Rubber has a service life, so rubber parts have become the most aging parts on the car, and they are replaced frequently. The most typical example is the tire, which has to be replaced every 3-5 years. There are also typical examples on the engine, such as valve oil seal and engine foot rubber. If the valve oil seal is not changed for a long time, the vehicle will inevitably burn engine oil.

Valve oil seal

There are also many rubber parts used in the automobile chassis, among which the ball cage sleeve is one of them. Many car owners are troubled by the ball cage oil leakage, which can be seen from the data of the repair vehicles in the garage. There are not a few vehicles coming to repair because of the half axle ball cage oil leakage.

The ball cage covers of some vehicles are seriously damaged, and most of the black grease in them has been thrown out. They all came to the garage for inspection because of the serious abnormal noise of the chassis. General vehicles are driven in different ways. For example, there are usually 4 or 8 ball cages represented by the previous four-wheel drive vehicles and four-wheel drive vehicles. There is an inner and outer ball cage at both ends of the half shaft. Each ball cage is protected by a rubber sleeve, which can prevent dust, moisture and other particulate impurities from entering the ball cage and prevent the leakage of lubricating grease.

Do not underestimate this rubber sleeve. Most of the problems of the ball cage are related to it. When the rubber sleeve is broken, the internal lubricating grease will be dried, and the external particle impurities and moisture will easily enter. The ball cage will be damaged due to dry grinding. At this time, the problem is serious. It costs about 100 yuan to replace the ball cage cover. If the ball cage is damaged, it will cost hundreds or even thousands of yuan to repair. Because the ball cage is worn out, it usually needs to be replaced together with the half shaft when going to the garage. Replacing the half shaft involves removing the gearbox, which will obviously be more troublesome.

When the ball cage sleeve is aged, the ball cage sleeve can be replaced directly. Generally, it only needs several steps, such as knocking down the ball cage or removing the half shaft, removing the bearing, replacing the sleeve and fixing clip. The process is simple and the price is cheap. However, if the aging of the cage cover is left unchecked, it may require more than 10 times the maintenance cost. Therefore, it is necessary to replace the rubber sleeve of the ball cage in a preventive manner. Do not wait until there is an abnormal noise, because the ball cage may have been injured when there is an abnormal noise.

There are two different reference points for the preventive replacement of the cage cover. First, for old vehicles with a mileage of more than 100000 km, the chassis should be regularly observed and the cage cover should be replaced immediately if it is found damaged; The other way is the safest, that is, after the vehicle has run for 100000 kilometers, directly replace all the cage covers to eliminate all hidden dangers.

Replace the ball cage

In other words, the preventive replacement of the cage cover should be based on the vehicle running over 100000 km, that is, if the cage cover has been used for more than 100000 km, it should be regularly observed or directly replaced.
