Without a proper seal driver, I've resorted to a short 2x4 laid over the seal and a hammer. Tap easy at first to make sure they are straight, then whack them in place. I haven't worked on a 1 ton, but that method worked on the axle seals on my '51 1/2 ton. As long as there's space around the seal for the 2x4 to not get hung up, it should work for you.
