The abnormal sound of Volkswagen Ling Du gearbox may be caused by poor oil quality, aging of valve oil seals and front and rear crankshaft oil seals, clogged air filter and oil filter, and unclean throttle valve.

Common abnormal sound of Volkswagen Ling Du gearbox and its solution: 1. There is abnormal noise in the cab when the car is idling or driving.

Insufficient transmission oil or oil deterioration; The transmission bearing is worn, loose or damaged; Bending of transmission shaft; Gear meshing is abnormal, and the meshing clearance is too large or too small; Metal on the gear tooth surface is peeled off, teeth are broken or assembly dislocation is repaired; The grooves of the shift lever and shift fork are loose. When the car is driving, there is a sound of dry friction of metal, and it feels very hot to touch the transmission housing with your hands. This is the noise caused by insufficient or deteriorated lubricating oil. You should refuel or check the oil quality and replace it if necessary.

2. The gearbox has abnormal sound in neutral. When the clutch pedal is depressed, the noise disappears. Generally, the front and rear bearings of the transmission shaft are worn, loose or often mesh with gears. If you change to any gear, it is mostly a two-axle rear bearing. For bearings that are seriously loose or damaged, repair or replace them.

3. Abnormal sound of gearbox When the vehicle is driving at a low speed, there is a rhythmic noise of "honk, honk, honk", but when the speed increases, it becomes a messy gear collision sound, and the gear shift is also loud, which may be caused by poor gear engagement of the transmission. If the noise is slight and even, you can continue to use it. If it is serious and uneven, it should be removed for inspection and readjusted or replaced if necessary.

4. Abnormal sound of the gearbox When the engine is idling, it makes a rhythmic "honk, honk, honk" sound, which is more serious when the throttle is increased. It feels that the transmission vibrates, which is generally caused by peeling off the tooth surface or breaking off the gear teeth. This sound will also be made if the gear center is offset after repair and assembly. In this case, it should be disassembled for inspection and replaced with a new one if necessary.

5. When the gearbox is running without rhythm and abnormal sound, a certain gear makes rhythmic and dull noise. When the gear lever is held by hand, the noise disappears, probably because the gear fork groove is worn or the working face at the lower end of the gear lever is worn, so it should be disassembled, inspected, repaired or replaced.

6. When the gearbox is hung in a certain gear, the noise is obvious after being hung in a certain gear, that is, the gear in this gear is excessively worn and rang. If it makes periodic noise, it is the damage of individual gear teeth. There was a sudden crash during the speed change operation, which may be that the gear teeth were broken. The transmission should be disassembled in time for inspection, repair or replacement.
