Extraneous noise in neutral position of the transmission:

 – are worn-out the bearing of an entrance shaft (noise is heard at the released coupling pedal);
 – the release bearing of coupling is worn-out.

Noise at inclusion only of one transfer:


 – teeths of a gear wheel of one transfer are worn-out or damaged.

Gear shifting is complicated:

 – coupling damage;
 – drafts of gear shifting are worn-out or damaged;
 – drafts of gear shifting are incorrectly adjusted;
 – synchronizers are worn-out.

Knocking-out of transfers:

 – draft of gear shifting is worn-out or damaged;
 – drafts of gear shifting are incorrectly adjusted;
 – synchronizers are worn-out;
 – forks of inclusion of transfers are worn-out.

Vibration:

 – low level of oil;
 – wear of bearings.

Oil leak:

 – wear of sealing rings of differential;
 – wear of consolidation of an entrance shaft.
