Doesn't really matter what side you take it apart from, just that you leave one side tight to keep the length adjustment. On a solid axle it matters even less as you don't need the length adjust to be so close. YOu may want to work with a shop to match up cones.

On a hub that has a freehub you always want to have the drive side tight and put the axle into the hub from that side...and do all of your adjusting from the NDS. Most hubs will not allow adjustment from the DS, the cone is generally too far inside the freehub to get a wrench on it.
