I tend to believe that M/B had some good reasons for using oil. The oil, if the boots are filled completely, will always be on the bearing surfaces. The grease will be flung to the outside of the boot, leaving the bearing surfaces without the desired lubrication, unless the boot is completely packed.
The longevity of these axles with the use of oil should give one pause before grease is selected for a replacement lube.
