I can't help with the videos online, but I did make my own tools to 1- remove the carrier, and 2- install the new seal.......
If you have access to a welder, the carrier removal tool is super simple to make, cost me $6. I bought a 6" piece of pipe bit enough diameter to fit around the inside of the carrier. I then cut notches in it to grab on to the 3 spokes inside the carrier. I welded on a 3ft. piece of steel pipe to it to add leverage for turning. First I remove the locking bolt inside the carrier, and it unscrewed very easily with this tool:
For the prop shaft seal installation tool, I had a 1ft. section of 1.5" pvc pipe, and a pipe cap. I filed down the INSIDE of the pipe, to form a somewhat of a beveled edge..... allowing the seal to fit snuggly on it. I then inserted it into the carrier, and a few wacks of the hammer on the pipe cap, installed perfectly!
Hope this helps a little!!!!!!!!
