cgordon,
As Andrew points out there are several endcap seals on each hub. I would check there first. These are specifically the endcap seals not the seals on the bearings.
1\. pull off the NDS endcap and add a light grease or oil to the lip of the seal.
2\. If running Shimano cassette body pull off the DS cap and add a light grease or oil to the lip of the seal. If running and XD body there is no endcap seal
3\. Pull off the cassette body and add a light oil to the lip of the cassette body seal.
You should be able to remove all endcaps without tools.
Hopefully this will improve the drag to and acceptable amount for you. If you live in a dry area you can also remove the endcap seals all together (but not the cassette body seal), same goes for the front.
