Outer CV Joint, Checking: Removing
-- Mark the position of the ball hub -3- to ball cage -2- and to housing -1- before disassembling, using an electric engraver or grindstone.
-- Pivot the ball hub -3- and the ball cage -2- and remove the balls -4- one after the other.
-- Turn the ball cage -2- until the two rectangular windows -arrow- are aligned with the joint housing.
-- Lift out the cage -2- with the hub -3-.
-- Swing a hub segment in a cage window.
-- Tilt out the hub -1- from the cage -2-.
The six balls for each joint belong to a tolerance group. Check the axle stub, hub, cage and balls for small depressions (pitting build-up) and chafing.
Excessive backlash in the joint is noticeable by a thump during load alternations. Replace joint in such cases.
Flattening and running marks on the balls are no reason to replace a joint.
