Almost every car drove for a long time，The engine noise will increase，Vibration will increase。This is even your diligent maintenance，Strictly follow the requirements of the instructions to replace all kinds of oils.。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 unsolved? Where is the problem with the noise vibration?。

Most of the vibration is the pot of machine feet

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 cause significant vibration。seabet loginThe engine vibration intensifies，In most cases, it is a problem of machine foot glue。

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 high temperature 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 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，You must go to the repair shop to do it，At the same time, because you want to lift the engine，Working fee for changing feet，It will be higher than the general engine maintenance。

The interior is basically no solution

In addition to the sound of the engine，The most often old car is the most strange interior.。Some of the abnormal noise you can’t distinguish between 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 hardened after a long time，Sounds of friction seabet appbetween parts after hardening。The place where the screw is fixed for a long time and will be loose after a long time，There will be abnormal noise when it is loose。The key is，The interior abnormal noise is basically not repaired。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?

Wind noise increases? Check the door secret seal!

Ecessage of wind noise is likely to be a calamity caused by the door densely blocked。The reason is very simple，One of the main functions of the door density seal is the sealing vehicle，Prevent too much wind noise into the cabin。The door sealing strip is also made of rubber，After a long time, it will be stiff，Of course I can't stop the leakage after having stiffness。

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 car doors of the entire car。

But there is a certain chance that after you change it, the wind noise is still so big，That is likely to be a wheel arch、The engine cabin firewall or the trunk and other places such as sound intervals are sculpted，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。
