Just squirt ATF or oil on the springs and go for a drive. The oil will migrate between the leaves. When I first bought my 29 Tudor, the springs were bone dry and lightly rusted, so the car rode like a lumber wagon. I squirted oil on them and drove it over the bumpy paths in the junk yard. It now rides quite smooth. Squirt them down a few times over a few weeks, and they will get lubed.
