Almost every car has been driven for a long time，The engine noise will increase，The vibrations will intensify。Even if you take good care of it，Strictly follow the instructions and replace various oils and the same problem will occur。Of course this phenomenon is easy to explain，The engine will age，With aging, there will definitely be problems of one kind or another。

But is this problem completely unsolvable?？What is the problem with the loud noise and vibration？In fact, it may not be complicated。

The vibration is mostly caused by the rubber on the machine’s feet

Although the engine body does wear out a little with age，The various matching accuracy inside the engine will be reduced，But this is actually far from the seabet iolevel that will cause obvious vibration。Intensified engine vibration，In most cases it’s a problem with the machine’s foot glue。

So-called machine foot glue，The term is engine shock absorber。Actually, it’s just a few rubber blocks placed between the engine and the metal frame。Due to the engine running at high temperature for a long time，Rubber itself is very sensitive to high temperatures，So the aging of machine foot rubber is inevitable。Aging machine foot glue will harden，Directly causing more engine vibrations to be transmitted into the cabin，Of course you will feel the engine running rough，The noise has increased and the vibration has increased。

The solution is simple，Just replace the machine foot glue。But this operation requires lifting the engine，You can’t do it alone，Must go to the repair shop，At the same time, because the engine needs to be lifted，The labor cost of replacing the foot glue，It will be higher than ordinary engine maintenance。

Except the sound of the engine，The most common thing in old cars is all kinds of strange interior noises。You can’t tell where there are some abnormal noises。These situations，Most of them are caused by abnormal noise in the interior。

Why does the interior make abnormal noise？Maybe you should ask why the interior does not make abnormal noise。The interior of a car is made up of many, many parts，With seats，Various panels，Various equipment，All kinds of miscellaneous things。How are these things fixed?？Basically all are seabet iofixed with screws or glue。

The glue will harden over time，After hardening, friction will occur between the parts and sound will occur。The screws will loosen over time，There will be an abnormal sound if it is loose。The key is，There is basically no possibility of repairing abnormal noise in the interior。Because it is impossible for you to find the one or two screws with abnormal noise among the tens of thousands of screws, right，Not to mention，How do you determine which screw and which glue is defective？

The increased wind noise is most likely caused by the door seal。The reason is very simple，One of the main functions of the door seal is to seal the vehicle，Prevent excessive wind noise from being transmitted into the cabin。The door seal is also made of rubber，It will become hard over time，Of course it can’t stop the air leakage after it becomes stiff。

So what to do？This is relatively easy to solve，Distinguish which door has the loudest wind noise，Just replace all the door seals on that side。If you have time，You can even find a day off，Just replace all the sealing strips on all the doors of the entire car。

But there is a certain chance that the wind noise will still be so loud after you change it，Then it is most likely the wheel arch、The sound insulation glue in places like the engine compartment firewall or trunk has hardened，It’s hard to replace that kind of place yourself，If you really can’t bear it，The only option is to go to the car maintenance shop for sound insulation。
