Inner CV Joint, Checking
It is necessary to disassemble the joint whenever replacing the grease or if the ball surfaces show wear or damage.
Disassembling
Ball hub and joint are paired and should be identified before removal. Do not interchange ball race allocation.
-- Tilt the ball hub and ball cage -1-.
-- Push the ball hub and ball cage -1- out of the joint in the direction of -arrow-.
-- Remove the balls from the cage.
-- Tip the ball hub -1- out of the ball cage -2- through the running path of ball -arrows-.
-- Check the joint, ball hub, ball cage and balls for small broken off depressions (pitting) and chafing.
Excessive backlash in joint will be noticed as a knock during load changes. Joint must be replaced in such cases. Flattening and running marks on the balls are no reason to replace the joint.
Assembling
-- Insert the ball hub into the ball cage via two chamfers. The installation position is arbitrary.
-- Push the balls -2- in the cage -1-.
-- Insert hub with cage and balls upright into joint piece.
- When inserting, make sure that in each case the wide gap -a- at joint piece contacts narrow gap -b- at hub after swinging in.
- Chamfer on inner diameter of wheel hub (splines) must face toward drive axle.
-- Swing in ball hub, to do so swing out hub far enough from cage -arrows- so that the balls have the distance of the races.
-- With strong pressure on the cage direction of -arrow-, pivot the hub with the balls -2- into the joint -1-.
Check the CV Joint Function.
The CV joint is properly assembled, if the ball hub can be slid back and forth by hand over the entire length adjustment.
-- Press in half of the total grease amount (40 grams) into joint body.
-- Distribute the remaining grease in the joint boot.
