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.
Removing
   
–  Before dismantling, mark position of ball hub in relation to ball cage and joint body with an electric scriber or oil stone.
–  Swing ball hub and ball cage.
–  Remove balls one at a time.
  V40-0015
–  Turn cage until the two rectangular windows -arrow- align with joint body.
–  Take out cage with hub.
  V40-0016
–  Swing segment of hub into square cage window.
–  Tip hub out of cage.
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. Smoothing and traces of wear of the balls are no reason to change the joint.
Installing
–  Pack half of total grease quantity (40 g) into joint body.
–  Fit cage with hub into joint body.
–  Press in opposing balls one after the other; the original position of the hub relative to the cage and joint body must be restored.
–  Fit new retaining ring into hub.
–  Distribute remaining grease in boot.
–  Checking function of constant velocity joint
The constant velocity joint is correctly assembled if the ball hub can be moved by hand backwards and forwards over its entire range of axial movement.
