Information
When replacing individual components on the front drive shafts, a mixed installation of different types of
components is not permitted. Only replace removed components with components that have the same
part number.

The optimized front drive shafts are not installed.
If one or both front drive shafts are damaged, both front drive shafts must always be replaced
by optimized front drive shafts with the Part No. 95B.407.271.C.  Workshop Manual 'Tools and
materials'
If front drive shafts were replaced with front drive shafts of a different type, the all-wheel
drive control unit must also be re-programmed.
