Driveshaft

Leaks in a forward part of the driveshaft

Defect of an epiploon of transmission or the transfer case takes place. The description of procedures of replacement see in the Head Automatic transmission. During replacement check the holder of a crosspiece equipped with vents for existence of the zadir, agnails and roughnesses capable to damage an epiploon. Agnails can be removed by means of a thin grinding stone or an emery paper.

At the time of the beginning of transfer of load of the transmission line (directly after installation of the transmission/check point on transfer) there are a knock or clicking

  1. Components of a back suspension bracket are disconnected or their fastening weakened. Check bolts and nuts of all support and tighten them with the required effort (The head Podvesk and steering). Check a condition of plugs of fixture (The head Podvesk and steering).
  2. Driveshaft bolts weakened. Check a condition of all bolts and nuts and bring up them with the required effort.
  3. Bearings of crosspieces of cardan hinges are worn-out or damaged. Check a condition of crosspieces (The head Stsepleniye and the transmission line).

At the movement of the car the metal clang constantly takes place

There is a wear of bearings of crosspieces of cardan hinges mentioned above (The head Stsepleniye and the transmission line).

Vibrations

Before coming to final conclusion about worthlessness of the driveshaft make sure that wheels correctly are balanced, then make the check described below.

  1. Establish in salon a tachometer for fixing of turns of the engine in the course of the movement of the car. During a trial trip you watch turns engines and record indications of a tachometer at the time of the maximum increase in intensity of vibration. Then switch transmission to other transfer and give turns of the engine besides to value.
  2. If vibration reaches the peak at the same value of turns of the engine, then not defect of the driveshaft as the speed of its rotation will be excellent is the reason of its emergence.
  3. If vibration disappears, or its intensity considerably will go down with transfer change, but at the same turns of the engine, then pass to the analysis of a possibility of existence of other reasons.
  4. The driveshaft can be bent or deformed. Check a condition of a shaft, in case of need make its replacement (The head Stsepleniye and the transmission line).
  5. Lumps of dirt or anticorrosive covering of the bottom of the car stuck to a shaft. Clear a shaft and repeat check.
  6. Bearings of crosspieces of cardan hinges are worn-out. Remove and check (The head Stsepleniye and the transmission line).
  7. Balancing of the driveshaft and/or connecting flange is broken. Check existence on a shaft of small weights of counterbalances. Remove the driveshaft (The head Stsepleniye and the transmission line) and install it into place, having turned on 180 °. If the situation did not improve, make professional balancing of a shaft.
