Inner CV Joint, Checking
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 the 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 running paths.
-- With strong pressure on the cage -direction of the 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.
