Because my car made some weird noises I decided to replace the matching CV joint. After removing it (I needed several sharp hammer blows) I discovered that the spline of the axle shaft was damaged.
The incision in the axle is needed for a matching clip to hold the CV joint.
Is this a common fault? Was it me with removing the CV joint or was it another factor and I found the source of the noise?
Edit: The debris is just completely detached from the axle, I was able to pick it out without any effort. At them moment the axle got re-installed with the new CV-joint-
