front axle seal ,dodge ram

2000 dodge ram 1/2 ton 4x4.Any tips/tricks to install outer seal on the right side of the front axle.I know there is a tool since the seal is inside the tube.I have the axle out and the actuator removed.I don't see a safe way of installing the seal straight.Any mcgiver tips?

I recently did both seals and u-joints on my '94. Just need a piece of all thread (I used 3/8") a couple nuts/washers and 2" hose clamp. Remove the band from the screw of the hose clamp, and use the band and a large washer to pull the seal into place. Use a large washer or piece of flat bar with a hole on the hub to pull against. This is the easy side. Gotta pull the carrier for the driver's side...

BTW, I would also remove the intermediate shaft. You'll need the room to work. and be sure to clean the axle tube out real good so you don't push junk back into your new seal. Spry some brake cleaner from the inside of the CAD housing out. Then drag a red rag through a couple times.
