CAUTION
If a shaft with an overly small diameter is used, the bearing of the knuckle eye will be
subjected to linear load. This subjects the inner bearing shell to excessive load, which can
lead to damage and, if forces are high, can cause the knuckle eye bearing to break.
Select the shaft as recommended in the mounting instructions.
2. Distance between knuckle eye and shaft bearing
The shaft support must allow for suitable play between the knuckle eye and the shaft
bearing.
