3.13. Check of a condition of protective covers of CV JOINTS of power shafts

Protective covers of power shafts are very important elements since they protect the hinges of equal angular speeds (HEAS) from the hit on them of dirt, water and other foreign matters causing damages. External pollution of protective covers oil and lubricants can lead to premature failure of material of covers therefore it is recommended to wash periodically covers with water with soap.


  1. Examine covers on existence of gaps and cracks, and also the weakened collars. In case of detection of signs of cracks or leak of lubricant the cover has to be replaced.
  1. At the same time check the general condition of CV JOINTS, holding a shaft and at the same time trying to turn a wheel. Repeat attempt, holding the internal CV JOINT and turning a shaft. Any noticeable side play indicates wear of the hinge, wear in grooves of a shaft or weakening of a lock nut of a shaft.
