Listening fault knowledge

Listening fault knowledge 1, abnormal sound body This problem is usually not enough because the body stiffness, resulting in vehicles in the deformation, friction, or the door frame with the car shake, or sealing off some areas arising from friction between the steel plate. Posted in the windows and doors in the friction parts of the pad or strip of rubber and other methods may be able to reduce or eliminate abnormal sound, but a temporary solution. Some of the larger vehicle wind noise, and shape it, and if confirmation is not adding unnecessary items, the owner would not even think about a solution of their own. There are fixed between the car body parts can also cause abnormal sound bad, the general tightening the screws can be solved. 2, abnormal sound engine compartment Here the possibility of abnormal sound more. Belt howling more harsh, generally because of the belt slipping due. When the engine is running dry if the external metal parts rubbing sound, usually generators, water pumps, power steering pump bearing damage performance. Leak when the engine is running the sound, it may be blocking the exhaust system, vacuum leak or rupture. Need to be reminded that if the engine within the abnormal sound, most owners can not be solved, it is best to send plant maintenance. 3, abnormal sound transmission If the transmission in driving the car within the "rustling" sound, and the clutch and then disappear, then the noise source is the transmission failure, it may be worn gearbox bearings or gears, bearings due to spots. 4, brake noise Brake brake disc brake friction screaming mostly sub-standard or excessive wear, brake lining material is excellent, can replace the soft brake pads. You can also use the brakes hard to knock down some of the grinder can be. 5, the tire abnormal sound Tires must be rhythmic sound, and the frequency of high-speed fast. If it is low "flap" sound, most of the deformation of the tire tread, from the package, badly worn or insufficient air pressure; if it is "blah" sound, the tread may be mixed with pebbles. If the tires whirring call to ring, and clear the body shake even the direction of deviation, that is certainly not the tire burst, get off the tire change it. 6, suspension abnormal sound A four-wheel encounters bumps around on the issue of "pound" or "click" sound, most of the shock absorbers or suspension parts loose causing the problem, be sure to shop carefully to the regular maintenance checks. Not only because of suspension components and ride comfort, but also on related to traffic safety, do not be discounted.
