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.
-- Remove the joint in the direction of -arrow-.
-- Remove the balls from the cage.
-- Flip out ball hub from ball cage via the ball race -arrows-.
-- Check the joint, ball hub, ball cage and balls for small broken off depressions (pitting) and chafing.
TIP:
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. Press balls into cage.
-- 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.
-- Swing in hub with balls by pressing forcefully onto cage -arrow-.
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 grease into joint body.
