First, the suspension system noise
 
     Although this is a normal aging category, but different users will be significantly different results. A large part of the hub bearing wear or shock absorber damping in the damping fluid due to reduced capacity. There are many examples of damping fluid leaked. Because the car's performance by damping fluid damping and spring together to complete, damping fluid loss of ability to make noise significantly increased.
 
     Auto Repair solution: is to go to car dealer’s repair, changing wheel bearings or shock absorbers.
 
     Second, the engine and its accessories noise
 
     This is due to long years while the engine internal components due to normal wear and tear. If you have previously had a non-normal incident, such as the oil had leaked over the same time not to be identified or has been leaked antifreeze. Have had such an engine noise will experience larger, depending on the size of the noise on the size of the accident.
 
     Auto Repair solution: is to replace some or all of the engine moving parts, such as connecting rod, connecting rod, piston and piston rings. Also due to some external accessories such as engine belt is not properly installed or in a long time due to wear and tear.
 
     Third, the exhaust pipe noise
 
     Belong to the category of normal aging. 10 years or 200,000 kilometers around the exhaust pipe, because of its frequent contact with mud and other underbody acid mixtures, or the possibility of leakage due to corrosion, then the body and tail of the noise increase, which generally can clearly hear out.
 
     Auto Repair solution: is to replace the whole or part of an exhaust pipe, the noise can be eliminated immediately.
 
     Fourth, the brake system noise
 
     Brake pads in the normal wear and tear if it is to continue to use, easy to wear to the brake disc brake shoe, brake will have a very shrill scream.
 
     Auto Repair solution: is to replace the brake pads (brake discs have replaced if they are worn)
 
     Five, body noise
 
     Normal perennial cause, usually caused by some parts of the relaxation due. At the same time, the traveling speeds of the noise. This is a resonance problem. Other non-listed above noise need more attention, and immediately removed, such as the steering system noise and electrical noise.
