Inner CV Joint, Checking

Inner CV Joint, Checking

Removing

The Constant Velocity (CV) joint must be disassembled to replace dirty grease or for checking the ball bearings and ball tracks for wear and damage.

- Swivel the ball hub and the ball cage.






- Remove the ball hub and ball cage in the - direction of the arrow -.

- Remove the ball bearings from the cage.

• The ball hub and joint piece are paired. Do not interchange.

- Flip out the ball hub from the ball cage via the running path of the ball bearings - arrows -.






- Check the CV joint piece, ball hub, ball cage and ball bearings for small broken off depressions (pitting buildup) and chafing.

Excessive circumferential backlash in the CV joint makes itself noticed via tip-in shock. The CV joint must be replaced in such cases. Flattening and running marks on the ball bearings are no reason to replace the CV joint.

Installing

- Insert the ball hub into the ball cage via the two chamfers. The installed position is at random. Press the ball bearings into the cage.






The ball hub has 2 different distances between the ball tracks, a larger and a smaller.

- Insert the hub with cage and ball bearings upright into the CV joint piece, a smaller space - b - must face toward the open side of the CV joint piece when doing this.






- Also note the chamfer on the inner diameter of the ball hub, it must be visible after swiveling in.

- Swing in the ball hub; to do so, swing out the hub far enough out of the cage - arrows - (as shown in the illustration).






- Swing in the hub with ball bearings by pressing forcefully onto the cage - arrow -.






- Check the CV joint for function.

The CV joint is properly assembled, if the ball hub can be slid back and forth by hand over the whole compensation length.
