i got a reallt easy way, k pull out axel, & inner axel, pull off vacuum pod,take a long rod 15" or so pop out the seal, k this is the easy part if dont have the speical tool , use two sael drivers and a long piece of treaded rod,1 seal driver sets on the utter end of tube which should b bigger in dia than the hole this 1 is where the axe u joint is the other seal driver will b slightly smaller than the seal this the one which will push the seal in place inside the tube, so run the theaded rod through the drivers and seal add nuts n washers , center the seal and start tightening, and tada u have the special tool, with seal in place, but dont over tighten it this will crush the seal, as will the proper tool will too!!just tighten it , them check it , dont force it , hope this hepls u
