New drive shafts - notes: Notes

As of the current '02 model (for exact delimitation see the spare parts catalogue), light-weight monobloc drive shafts -B-  are being used instead of friction-welded drive shafts -A-  in all 911 Carrera (996) models with manual and Tiptronic transmission. See Fig 1 . Drive shafts -A and B-  differ with regard to dimensions -1 and 2-  while dimension -3-  is the same in both drive shafts.

Manual transmissions and Tiptronic drive shafts also differ with regard to length in both the monobloc version -A-  and the friction-welded version -B-  (see the spare parts catalogue). See Fig 1 . To distinguish between the two, new drive shafts are labelled accordingly.
