Repair and operation of the car

Zadny Bridge consists of a beam, a reducer and half shafts. The reducer consists of gipoidny main transfer and differential. The axis of the leading gear wheel of the main transfer is displaced concerning the axis conducted down. Cases of half shafts of a vpressovana in a reducer case are also scalded on a contour.

On all-wheel drive cars the independent forward leading axis which consists of a reducer and 2 half shafts is established. On each half shaft there are internal and external CV JOINTS.

On a part of cars back differential self-locking with limited slipping which provides alignment of speeds of rotation of half shafts at loss of coupling of one of wheels with the road.

Usually increased noise is not connected with abnormal work of the bridge (axis). It is necessary to draw a conclusion about malfunction of the bridge only after an exception of other reasons.

The increased noise can be associated with noise from other sources than the bridge (axis):

 – noise from a paving. It is excluded by a trip around the road with a qualitative covering, or comparison to noise at the movement with dispersal or a setup;
 – noise because of insufficient pressure in tires or at wear of tires. It is excluded by a trip with dispersal or a setup;
 – noise from transmission or the engine. It is excluded by listening of operation of the engine at the motionless car on those turns on which noise is most expressed.

It is independently possible to perform only those works which content is considered below. Novy Bridge is selected on the stamp put with the manufacturer on a bridge beam.
