Caution Wheel bearings must not be subjected to load after loosening bolt securing drive shaft at wheel hub. If they have to support the weight of the vehicle they will be damages and their service life will be reduced. It is not permissible to turn drive shaft bolt more than 90º anticlockwise if vehicle is standing on its wheels. Do not attempt to move the vehicle without the drive shafts fitted; this would result in wheel bearing damage. If it is necessary for a vehicle to be moved, please comply with the following instructions:
