8.4.3. Check of a condition of driveshafts

At emergence of vibrations at high speeds of movement it is necessary to check size of palpation of driveshafts first of all.


  1. To Poddomkratta the car also establish it on props (see an illustration the Scheme of an institution of props for car fixing in the lifted situation).
  2. Attentively examine driveshafts on existence of deformations and other mechanical damages.
  1. Manually turning a connecting flange of the corresponding main transfer, measure size of radial palpation of the driveshaft by means of a tsiferblatny measuring instrument of plunzherny type.
  1. If the result of measurement leaves for repartitions of an admissible range (see. The transmission line, Specifications), disconnect a shaft from a flange of the main transfer, turn it on 180 ° and again connect. Repeat measurement — at negative results of measurement replace a shaft.
  1. If noise in the central bearing took place, make its replacement.

Check on a workbench


  1. Remove the driveshaft, lay it in V-shaped blocks and measure size of radial palpation. If the result of measurement exceeds limiting admissible value according to Specifications (see. The transmission line), replace a shaft.
  1. Estimate size люфта in the kardanny hinge of a shaft — if люфт exceeds admissible value (see. The transmission line, Specifications), also make shaft replacement.
