This is what I do but I have access to an air compressor, solvants and red wheel bearing greese. I pop the seals out with a pick and drop them on a bucket of solvent. then blow the crap out. spray with wd-40 (I have penzoil ZQ4)and blow more crap out till they spin freely. Then pack the red greese in both sides. Put the seals back in. Presto all done.
