I just reread this post and I have two more tip to install the axles seals. Instead of trimming the rubber off the outside of the seal I made a ring compressor ( like a piston ring compressor) out of .010 shim stock and a hose clamp. Installed the seal in the tube and taped it with a block of wood. They slid right in. Gary Jones gave me a tip. He said to pack grease inside the seals. He said this will help reduce heat.
