Furong District lofty Road Ma Poling (Mapo Road Primary School opposite) Changsha most regular car maintenance since the Baltic to the outside noise is very good, so some noise but the car itself seems relatively serious. In my experience, collect the following contents for your reference. 1) When the uphill sound (rubbing sound, sound more pointed): the front suspension lower arm pouches ring. The sleeve is a hollow structure, after the sound generated by the extrusion deformation, deformation front wheel uphill most serious. Solution: lubricating the sleeve. Sound (reversing particularly evident) is the most formal start turning Changsha car maintenance 2): front wheel bearing ring. Mainly on a small number of early 02 models. Because this part of the car outside the Cage shaft shorter, matching hex nut is shaped, installed after tight enough, causing bearing loose. Solution: Replace self-locking nut, if necessary, change the drive shaft. 3) Start or flame, when Britain is quite ring road: gearbox bracket rubber ring. Plastic hollow structure, mutual friction extrusion deformation, resulting in abnormal sound. In the above case, the maximum jitter engine and gearbox. Solution: Replace the bracket lubrication or glue. 4) Rear brake pads response: brake pads and discs caused. Usually this happens after wet water due to brake sheet metal content increases (performance, environmental requirements), while the brake handle, so quickly formed between the sheet and the rust plate, step on the brake when the rust In the friction caused by abnormal sound; if long dwell time, rust layer thickness, may not step on the brake when the rear wheel will ring. 5) high-speed four-wheel noise: tire ring. POLO four bearing performance extremely reliable, generally does not produce noise, tire pressure is too low will cause abnormal sound, even after additional wear and tear caused serious noise. Solution: Adjust air pressure, replace the tire. 6) chassis during acceleration response (broken metal sound): catalytic converters ring. TWC middle soft connection acceleration vibration, abnormal sound. Solution: Replace the catalytic converter. 7) On the front of the loud air conditioning (with the wind): cooling the motor sound. Cooled motors have high and low, high-end speed than the ring, normal. Such as high-end running frequently, will have to check the status of the two fans. Solution: Replace the fan. 8) before the air conditioning unit sound (whining): compressor ring. Just started or have a slight sound is normal, as is the continuing failure of large loads. Workaround: change the compressor. Rang the front (front of the engine) 9) After starting: pumps ring. Sound more pointed, with speed increases and increases. Solution: Replace the water pump. Changsha most regular car maintenance 10) start after a rear impact (current sound): fuel pump sound. If, in a quiet environment, you carefully listen to the rear wheels, you'll hear the sound of a small electric current, which is a normal phenomenon. If in a noisy environment or rear of the vehicle can obviously hear the sound, then the fuel pump is certainly a dirty or clogged fuel filter. Solution: Clean or replace the fuel pump. 11) when the rear door ring (current sound): fuel pump sound. You opened the door, POLO already know that you want to start, so the pumps start working, then you twist it with a car key. As long as the sound is not particularly large, normal. 12) dashboard ring: Because dashboard material expansion and contraction is relatively large, so it is easy to generate frictional sound expansion on hot days. Workaround: disassembly dashboard, key parts of the paste special tape. 13) The rear shock seat ring: the sound of small, crisp. Seat cushioning BOOT file could not silt, sediment entering damping seat after dry grinding, produce the sound. Workaround: lubrication or replacement (new state). 14) Rear Britain quite similar sound :( 13) Since the backrest caused by loose ring can be set off after the backrest, adjust lock position. Changsha most regular car maintenance 15) Transmission ring (slight gear ring): idling sound start, after the disappearance of the clutch pedal, the more obvious when the air conditioning. Since the load is large, the error on the manufacture and assembly of the gearbox input shaft so that radial runout, resulting in transmission gear ring. 16) emergency fuel door ring (crisp clatter): low grade of gasoline cause engine knock. Solution: Replace the high-grade gasoline. Changsha most regular car maintenance
