GENERAL INFORMATION

Define the mode of the movement when noise is shown most often. It is necessary to distinguish:

1) Noise at dispersals.

2) Noise at the movement of the car a setup.

3) Noise at uniform motion of the car on the flat road (at extremely low speed for this transfer).

Noise from movement along the road

Noise when driving on the road with a paved or concrete covering can be confused easily with noise from the back bridge. This type of noise is similar on arising in the modes 1) and 2). It is excluded by comparison to noise when driving on the road with other covering.

Noise from wheels

Noise from wheels usually take for noise from the back bridge. The additional mistake is brought by tires with a winter protector or unevenly worn-out tires. If it is temporary to pump up the tire to 2,5 atm, then the nature of noise has to change strongly, but at the same time also the noise proceeding from the back bridge will change (which as a rule stop at a speed below 50 km/h).

Noise from the engine and transmission

Determine the speed at which noise is listened most distinctly then stop the car in the quiet place. Start the engine and finish turns to corresponding to speeds of the movement at which noise was listened. Noise which proceed from the car are caused by the engine and transmission.

Noise from forward wheels


Moving with a constant speed, slightly press a brake pedal. At the same time noise from bearings will decrease a little.

Noise from the back bridge

The exception of the noise stated above will allow to allocate the noise caused only by the back bridge which are caused only by wear of gear wheels of a reducer or bearings. Noise from gear wheels is listened in the narrow range of speeds, and noise from bearings only changes tone at change of speed of the movement.
