Chris at Memphis Trucks taught me a really easy way to remove the front axle inner oil seals for replacement. I would like to share it with my fellow soldiers. This is done after removing the front brake assemblies, bearing spindles and axles. You simply take a 10' long piece of 1/2" steel pipe with a threaded cap on the end, insert it all the way through the axle housing and differential and tap it a few times with a three pound hammer. The seal should pop right out. Do the same thing from the opposite side for the other seal. Just make sure that the pipe cap is contacting the inner side of the metal seal and not just going through the seals hole. I tapped at the top and then the bottom of the seal. I know you guys might already know this, but I thought I'd share for those that don't and my be contemplating doing the work.
