Front wheel bearing grease change every 60 000 km's — VW

Previously wheel bearing grease had to be changed at 30 000km intervals for Taxi units only

Further tests have shown that this interval can now be changed retrospectively to every 60 000 km's i.e. 60 000, 120 000, 180 000 km's, etc.

For the above services the time remains at 340 T.U.

For older vehicles, please relay this information to your customer when carrying out these services

The In-Car Package Service Schedule Booklet will be updated when next printed

Note:

When re-packing, it is of the utmost importance that the hub and bearings are cleaned thoroughly, only Agip 33 FD grease is used and that the wheel bearing adjustment is carried out correctly. Refer to Running Gear S.A. Bulletin No. 6* for further information
