Yes.

Following the Parktool article I linked above is a lot easier than working both sides at once. The problem there is that once you've loosened locknuts and cones on both sides, it's just a lot harder to keep things from moving around on the axle once you've got the cones adjusted just so. I used to do both sides, then learned to do it with the bike frame, and it takes 1/4 the time with better results.

Another bonus is you only need one cone and one wrench.
