10.9. Check and replacement of CV JOINTS and their protective covers

Some automobile agents deliver protective covers of "cutting" type which can be established without removal of a power shaft from the car for replacement (they easily turn back around the hinge after cutting of an old cover). It is very convenient; however authors of this manual recommend to remove after all a power shaft, to clean the CV JOINT from dirt and moisture which reduce the term of its service and to establish a new integral protective cover.


If you noticed the signs of wear of the CV JOINT (which are usually caused by damage of protective covers), they should be replaced - both hinges can be replaced in an individual order.


Completely restored power shafts can be got but an exchange basis that will help to save a lot of time and forces. Anyway before dismantling of the car learn the cost and degree of availability of all details.

Check

It is regularly necessary to examine CV JOINTS and their protective covers, and every time when you lift the car. The car and reliably establish to Poddomkratta it on axial support. Examine protective covers of CV JOINTS on existence of cracks, leaks and the broken tightening tapes. If lubricant follows through a hole or a crack in a protective cover, it will result in premature wear of the CV JOINT and need of its replacement. Replace the damaged covers immediately. Having grasped serially each of power shafts, rotate them in both directions and move them inside and outside to check whether there is a side play indicating wear of shlits or weakening of landing of hinges.
