Checking outer constant velocity joint
Checking outer constant velocity joint
The joint is to be dismantled to renew the grease if it is heavily soiled, or to check the running surfaces of the balls for wear and damage.
Dismantling
   
–  Before dismantling, mark position of ball hub in relation to ball cage and joint body with an electric scriber or oil stone (arrow).
–  Swing ball hub and ball cage.
–  Remove the balls one by one.
  A40-0172
–  Turn cage until two cage openings -arrow- are level with joint body.
–  Take out cage with hub.
  A40-0155
–  Swivel one segment of the hub into one of the cage openings.
–  Remove the hub from the cage.
Checking
The six balls for each joint belong to a tolerance group. Check stub axle, hub, cage and balls for small indentations (pitting) and traces of seizing. Too much circumferential backlash in the joint becomes noticeable during load change jolts; in such cases, the joint must be renewed. Smooth areas and ball running marks do not constitute grounds for joint replacement.
Assembling
–  Fit cage with hub into joint body.
  Note
Make sure cage is inserted in correct position (i.e. sides facing in same direction as original position).
–  Press in opposing balls one after the other; the original position of the hub relative to the cage and joint body must be restored.
–  Pack grease into joint body; refer to for quantity and type of grease.
