| 1. Lift a back part of the car and record on supports. |
| 2. Rotating a back wheel, examine rubber protective covers of hinges of equal angular speeds, squeezing them for disclosure of bends. Check them for existence of cracks which can lead to lubricant leak, and also to penetration in water and dirt (see the drawing). |
| 3. Also check a condition of fixing collars, examine covers of internal hinges and casings on the other hand. If any damage is found, then the protective cover needs to be replaced immediately. |
| 4. At the same time check the general condition of hinges of equal angular speeds, holding a shaft and at the same time trying to turn wheels. Repeat attempt, holding the internal hinge of equal angular speeds and turning a shaft. Any noticeable side play indicates wear of the hinge, wear in grooves of a shaft or unscrewing of a lock nut of a shaft. |
