Almost every car drove for a long time，The noise of the engine will increase，Vibration will increase。This is even your diligent maintenance，Strictly replacing various oils in accordance with the requirements of the instructions。Of course this phenomenon is good to explain，Movement opportunity aging，As aging, it will definitely bring such problems。

But is this problem completely completely unsolvable? Where is the problem with the noise vibration?。

Most of the vibration is the pot of machine feet gum

Although the engine body does have a bit of wear with the increase of the year of use，Various coordination accuracy inside the engine will be reduced，But this is actually far from reaching the extent that it will seabet appcause significant vibration。The engine vibration intensifies，In most cases, it is a problem of machine feet gum。

The so -called machine foot glue，Term is called engine shocking seat。Actually, a few rubber blocks in the middle of the engine and metal frame。Because the engine is running in a high temperature state for a long time，and what kind of rubber itself is very sensitive to high temperature，So the aging of the machine feet is inevitable。Aging machine foot glue will harden，directly leads to the engine vibration more into the cabin，Of course you will feel that the engine is running rough，Noise increased the vibration。

The solution is very simple，Change the feet of the machine is。But this operation requires the hair to lift the motor，Not you can get it alone，Must go to the repair shop to do it，At the same time, because you want to lift the engine，Working fee for changing the foot glue，It will be higher than the general engine maintenance。

Except the sound of the engine，The most often old cars are the most strange interior abnormalities。Some abnormal noise, you can’t tell where you are at all。These situations，Most of them are problems with interior abnormalities。

Why does the interior abnormal? Maybe you should ask why the interior will not be abnormal。The interior of a car is a lot of components to fight，Have a seat，Various panels，Various equipment，Various miscellaneous things。How do these things be fixed? Basically all are screws or glue fixing。

The glue time will be hardening after a long seabet logintime，Sounds of friction between parts after hardening。The place where the screw is fixed for a long time and will loosen，There will be abnormal noise when it is loose。The key is，The interior is basically not fixed。Because you can't find the two abnormal screws in tens of thousands of screws at all, right?，Not to mention，How do you determine which screw and the glue is wrong?

Ecesss of wind noise are likely to be a disaster caused by the door density。The reason is very simple，One of the main functions of the door density seal is the sealing vehicle，Prevent excessive wind noise into the cabin。The door sealing strip is also made of rubber，After a long time, it will be stiff，Of course, after stiffness, I can't stop the leak。

So what should I do? This is relatively easy to solve，Disceiving which side door wind noise is the largest，Replace all the door sealing strips on the side is。If you have time，You can even find a rest day，Directly replace the sealing strips of all the doors of the entire car。

But there is a certain chance that after you change it, the wind noise is still so big，It is very likely that it is a wheel arch、Engine firewall or trunk and other places such as sound interval hardening，It is difficult for you to replace that kind of place，If you can't bear it，I can only go to the car maintenance store for sound insulation。
